Micro-Aid CLS+ is an admixture designed specifically to enhance the stability of low strength (lean) grout mixes. Micro-Aid CLS+ prevents segregation in mixes with very low cementitious contents, ensuring that pumping equipment will not become blocked. It also allows the user to significantly increase the water content to improve workability and further reduce strength. Micro-Aid CLS+ is particularly helpful when fly ash is not available and it is necessary to keep strengths low while maintaining a workable consistency. Micro-Aid TCA meets the requirements of a Type S, specific performance admixture according to ASTM C 494.
