Plastobuild ES is a superplasticising admixture that contains synthetic polymers.It is chloride free and is specially formulated to impart rheoplastic qualities to concrete. Rheoplastic concrete is a fluid concrete with a slump value of at least 200mm that flows easily but at the same time is free from segregation and has the same water/cement ratio as that of a no-slump concrete (25mm) without admixture. Plastobuild ES has been formulated to meet the requirements of ASTM C494 Type A & F and BS EN 934-2 Tabel 3.1 & Table 3.2. Plastobuild ES is compatible with all cement meeting recognize international standards. Plastobuild ES is compatible with most admixture types except with polycarboxylate ether based admixtures.
