The increased quantity and quality of cement paste provided by Enhance PMT admixtures gives the precast producer exactly what is desired in most mixes:
Within reason, slump may be adjusted using only added water. PMT’s are very good water managers. Water content may be adjusted in block mixes to improve paste volume and reduce efflorescence associated with low slump mixes. Block becomes more waterproof without the use of polymers.
Colored products are easier to manage. PMT treated cement paste is more color-fast with better control of leaching. In addition, thousands of dollars can be saved on the cost of acid washing efflorescence covered panels. Sharp bright colors are maintained and customer satisfaction is improved.
Surface sealing for best results is completed with use of EPC-150 or EPC-300. A surface repellent material may be used for graffiti or surface moisture concerns such as sprinklers, where iron may deposit from evaporated municipal water supply.
