Concrete is no longer just cement, sand, and gravel – it’s a high-tech material enriched with chemical admixtures and fibers that unlock new levels of performance. ZRETE’s Concrete Additives Solutions leverage cutting-edge R&D to tackle common challenges in concrete construction, from moisture penetration and rebar corrosion to shrinkage cracking and slow strength gain. By using our specialized additives, builders and engineers can extend the lifespan of structures, accelerate construction schedules, and achieve superior strength and durability in every project.

Durability & Waterproofing Additives

Protecting concrete from water ingress, chemicals, and rebar corrosion is vital for long-term durability. ZRETE offers integral waterproofing and protective admixtures that shield concrete from within, eliminating the need for external membranes or coatings. These additives enhance concrete’s resistance to harsh environments, ensuring structures remain sound and serviceable for decades:

• FSA101 Mortar Waterproofing Agent – A high-efficiency admixture that renders concrete and mortar impermeable. FSA101 penetrates the cement matrix to block capillaries and pores, providing deep waterproofing and preventing water-related damage like efflorescence and rebar rust. This additive is ideal for foundations, tunnels, pools, and other structures requiring long-term water-tightness.

• 402C Oil-Proof Concrete Additive – A specialty admixture that transforms regular concrete into a tough, oil-resistant material for industrial floors, parking garages, and chemical containment areas. By densifying the concrete and “locking out” oil seepage, 402C protects surfaces from petroleum products, solvents, and other contaminants that can cause deterioration. It also improves abrasion resistance, making concrete floors last longer under heavy traffic.

• H-501 Rebar Corrosion Inhibitor (Steel Savior) – An advanced passivating admixture that defends steel reinforcement against corrosion – often termed “concrete cancer” – especially in coastal or de-icing salt environments. H-501 migrates to the rebar and forms a self-healing oxide film (“armor”) on its surface. This protective barrier blocks chloride ions from reaching the steel, significantly extending the structure’s service life. Unlike some inhibitors, H-501 even boosts the concrete’s 28-day strength by reducing internal micro-cracking, ensuring protection without compromising structural performance.

High-Performance & Strength-Enhancing Additives

Modern construction often demands concrete that gains strength rapidly or reaches extremely high ultimate strength. ZRETE addresses these needs with high-performance additives that improve cement hydration efficiency and concrete microstructure, allowing faster turnaround and higher load capacities:

• UHPC Additive (Ultra-High Performance Concrete Enhancer) – A formulated mineral admixture that when added to concrete produces ultra-high performance concrete with superior compressive strength (well over 100 MPa), enhanced ductility, and durability. This UHPC enhancer optimizes particle packing and pozzolanic reactions, enabling infrastructure like bridges, high-rise buildings, and wind turbine foundations to achieve exceptional strength and longevity. It helps create dense, low-permeability concrete that resists abrasion, impact, and environmental attack.

• XT30 Early Strength Cement – A special rapid-hardening cement (and admixture system) that accelerates early hydration to attain high strength in the first 24–72 hours. XT30 is a high-early-strength binder that can be used as an alternative to ordinary Portland or CSA cements in time-critical projects. By using this cement, repairs and new constructions can bear loads sooner, even in cold weather or overnight pours. It’s ideal for urgent roadway repairs, fast-track precast production, and winter concreting, where gaining strength quickly is paramount.

• CBGM-300 Cementitious Grouting Additive – A high-performance grout admixture designed to produce flowable, non-shrink, high-strength grout by simply blending with local cement and sand. CBGM-300 simplifies on-site grout preparation for anchoring bolts, machine bases, or filling voids. It yields grout with exceptional early strength (≥20 MPa in 1 day) and ultimate strength (60 MPa at 28 days) while ensuring zero shrinkage and stable volume. This additive enables cost-effective yet reliable grouting for structural connections, precast assemblies, and repairs, meeting or exceeding the performance of pre-packaged non-shrink grouts.

Fiber Reinforcement Solutions

Dispersing fibers in concrete is a proven method to increase tensile capacity, improve toughness, and control cracking. ZRETE provides both synthetic PVA fibers and high-strength steel fibers to create fiber-reinforced concrete that can withstand heavy loads and dynamic forces with reduced risk of fracture:

• Spiral Polyvinyl Alcohol (PVA) Fiber– High-modulus PVA fibers engineered for concrete reinforcement (notably used in wind turbine foundation slabs and anti-cracking overlays). These synthetic fibers distribute throughout the mix, bridging micro-cracks as they form. The result is concrete with greater ductility, fatigue resistance, and post-crack load-bearing capacity. PVA fiber reinforcement is especially beneficial in large foundation mats, slabs-on-ground, and any concrete subject to cyclic loading or shrinkage stresses – significantly reducing crack width and improving durability.

• LEIKESI Copper-Coated Steel Fiber – Premium micro steel fibers with a copper coating for enhanced bond and corrosion resistance in concrete. When mixed into concrete or UHPC, these high-tensile-strength steel fibers act as microscopic reinforcing bars, increasing impact resistance, flexural strength, and overall toughness of the concrete. The copper coating protects the fibers from rust and ensures good long-term bonding with the cement paste. LEIKESI fibers are ideal for ultra-high performance concrete, tunnel linings, industrial floors, bridge decks, and other applications where conventional rebar might not prevent localized cracking or brittle failure. By using steel fiber reinforcement, structures gain ductility and energy absorption capacity, allowing them to better withstand earthquakes, blasts, and heavy loads.

Shrinkage Compensation & Crack Control

As concrete cures and dries, it can shrink and develop cracks, particularly in mass concrete pours or restrained elements. ZRETE’s shrinkage-control additives counteract this natural tendency by producing controlled expansion or reducing shrinkage forces, thereby preserving structural integrity and watertightness:

• T60 CSA-Based Expansive Agent – A calcium sulfoaluminate (CSA) based expansive admixture that generates early-age expansion in concrete to offset drying shrinkage. T60 is added to the mix to create shrinkage-compensating concrete that, upon curing, can expand slightly and fill internal voids. This prevents the formation of shrinkage cracks and joints, making it invaluable for large floor slabs, concrete tanks, basements, and repair overlays that need to remain crack-free. The controlled expansion from T60 also improves concrete’s density and long-term durability by minimizing pathways for water ingress.

• Magnesium Oxide (MgO) Shrinkage-Reducing Admixture – A novel expansive agent utilizing magnesium oxide that hydrates slowly to produce delayed expansion, countering the gradual shrinkage that occurs in the weeks after casting. MgO admixture is especially useful in massive pours (dams, foundations, mat slabs) where thermal and drying shrinkage over time can lead to cracking. By tailoring the grade of MgO, the expansion can be timed to the concrete’s shrinkage curve, achieving a net zero-shrinkage concrete that remains dimensionally stable and tightly crack-resistant.

• Calcium Magnesium Composite SRA – An advanced composite shrinkage reducing admixture that combines calcium-based early expansion with magnesium-based later expansion in one system. This two-stage approach yields complete shrinkage compensation: the calcium phase counteracts plastic and early drying shrinkage, while the MgO phase compensates long-term shrinkage. The result is a concrete that experiences virtually no net shrinkage from curing through service life. By using the Calcium-Magnesium Composite expansive agent, large-volume concrete structures (tunnels, rafts, reservoirs, runways) can be placed without contraction joints, significantly reducing maintenance and ensuring water-tightness. Structures gain enhanced durability and load capacity since shrinkage cracking – a primary cause of weakness – is eliminated at the source.

Pervious Concrete & Specialty Solutions

Sustainability and special application needs are also addressed by ZRETE’s concrete additives. For example, managing stormwater runoff is increasingly important in urban design, and pervious concrete is a key solution. Our additives ensure that even these specialty concretes achieve the required performance:

• Pervious Concrete Binder – A custom binder system formulated to produce porous, water-permeable concrete with sufficient strength. This solution allows construction of pervious pavements and drainage layers that rapidly infiltrate rainwater, reducing surface runoff and helping to recharge groundwater. ZRETE’s pervious concrete binder improves the cohesiveness of open-graded mixtures, preventing clogging and enhancing load-bearing capacity so that permeable parking lots, driveways, and sidewalks remain durable under traffic. It strikes an optimal balance between permeability and strength, enabling eco-friendly infrastructure without sacrificing performance.
