Next-generation high-range water reducer for concrete and mortar. PCE disperses cement efficiently to deliver very high water reduction and excellent flow while maintaining cohesion—ideal for ready-mix, precast, SCC and UHPC. Advanced PCE systems are known for strong slump-/workability-retention and can be supplied in liquid or powder grades for dry-mix lines.
Melamine-based superplasticizer favored for fast plasticization, low air entrainment, and high early strengths—commonly used in precast, white cement products, grouts and gypsum-based mixes. Reputable SMF lines meet high-range water-reducing standards (e.g., ASTM C494 Type F) and are available as liquid or spray-dried powder. Typical competitor literature lists ~0.5–1.5% bwoc dosage (optimize via trials).
Foam-control additive for cementitious systems (dry-mix mortars, tile adhesives, gypsum plasters, self-leveling compounds). Available as powder for dry blending or as liquid systems (oil-, silicone-, or EO/PO-based), defoamers reduce entrapped air and pinholes to improve surface finish and strength. Typical powder-grade dosages in dry-mix are in the ~0.05–0.2% range.
Set-time controller for calcium-sulfate binders (boards, blocks, plasters, self-leveling). Modern protein- or polymer-based retarders extend open time at very low dosages without sacrificing final strength, and are designed to be compatible with typical gypsum additives (plasticizers, surfactants, wetting agents). Offered in liquid or powder for continuous dosing or dry-mix.
Rheology modifier that increases cohesiveness, reduces segregation/bleeding, and keeps flow stable in highly workable mixes (SCC, pumpable grouts, lean mixes, manufactured sands). Chemistries include cellulose ethers, gums/biopolymers, colloidal silica, and tailored polymer VMAs. Products are marketed to meet VMA classifications (e.g., EN 934-2 T.13) and are typically liquid for concrete or integrated into dry-mix.
Non-sag, anti-settling builder for mortars, sealants, adhesives and repair systems. Thixotropes create shear-thinning behavior: stiff at rest (vertical hold) and fluid under shear (easy troweling/pumping). Common choices include fumed silica (hydrophilic/hydrophobic HDK® grades) and organoclay/hectorite systems, selected by chemistry (cementitious, epoxy, PU, solvent/waterborne).
