Costar Block 10 is a biodegradable admixture for masonry blocks specifically designed for manufacturing of hollow blocks. It provides a more efficient utilization of mixing water thereby enhancing workability, moldability and appearance of the masonry unit. it is designed for use with zero or low slump concrete commonly used in the manufacture of masonry blocks and is compatible with all types of Portland cement. Costar Block 10 exhibit improved enhanced cohesion, moldability, and increased early age strength when added to a mortar mix. It functions by improving more efficiently the utilization of mixing water thus aiding the dispersion of cement particles. Costar Block 10 can be utilized where an improvement in appearance of the masonry unit is required.

COSTARCEL 100 is a chloride-based concrete set accelerator, supplied as a ready-to-use liquid admixture. It significantly accelerates the initial setting time of mortar and concrete, making it up to three times faster than normal, without causing any adverse effects on other concrete and mortar properties.
By incorporating COSTARCEL 100, workability and strength of the mixture are improved while promoting faster cement hydration. This results in easier placement of the mix and speeds up construction by reducing the initial set and curing time, all without causing any slump loss. The use of this admixture allows for earlier removal of formwork and other protective measures and enables an earlier start to finishing, saving both time and labor.
In applications requiring very high early strengths under normal and hot weather conditions, COSTARCEL 100 performs exceptionally well. It is specifically designed for situations where early stiffening (slump loss) is not desirable, yet high early strengths must be achieved within a specified time frame.

COSTARCEL 200 is a ready-to-use liquid accelerating admixture for concrete. It accelerates initial setting time one to three times faster than normal mortar and concrete without adversely affecting other properties of concrete and mortar.
COSTARCEL 200 improves workability and strength while hastening the hydration of cement. It makes the mix easier to place and speeds construction by shortening the initial set and curing time without resulting in slump loss. Time and labor are saved because formwork and other protection can be removed earlier and finishing can be started.

CostarMix CR presents an effective remedy for preserving concrete integrity against chloride-induced corrosion, thus prolonging the durability of reinforced concrete structures. Within the alkaline milieu of concrete, an intrinsic ferric oxide shield naturally forms on embedded reinforcing steel, guarding it against corrosion. By reintroducing the protective layer on the steel surface, the CostarMix CR admixture significantly retards the corrosion process in reinforcement. The incorporation of nitrite ions within CostarMix CR admixture serves a pivotal function in forestalling the creation of ferrous chloride complexes. These nitrite ions proactively interact with defective ferrous oxide ions, preempting chloride-triggered corrosion and stabilizing the passive layer, thereby curtailing the risk of corrosion.
