The 23 types of Concrete Admixtures(Additives)used in Concrete

Common water-reducing agent is a wood quality sulfonate of chemicals. When added to concrete, it can produce the desired slump in a case where the water-cement ratio lower than usual design. It usually reduces the required water content of the concrete mixture by about 5% to 10%. Therefore, compared with untreated concrete, concrete containing water reducing
