Within the construction process in summer time, because of hot temperature within the concrete mixing process and faster cement hydration and moisture evaporation speed concrete block making machine supplier, the concrete slump loss is larger. Therefore the slump loss is a concern which must be more conscious of. To be able to prevent excessive slump from losing, we make use of the composite technology which mixes water-reducing admixture and sugar calcium retarder. Fraxel treatments may change coagulation and solidifying rate as well as effectively control the concrete slump loss. Daswell concrete pump has numerous advantages, however nowadays we'll introduce the classification of concrete pumpHenan Daswell Machinery is a professional manufacturer of mining machine for almost 30 years in China.

Its primary parameters would be the boom height and theoretical offerring volume. The boom height and theoretical offerring volume happen to be serialized. 1. Based on concrete pump boom height small mobile brick making machine, it may be split into short arm, lengthy arms SICOMA MPC mixer planetary, and super lengthy boom. 2. Based on the theoretical offerring amount of concrete pump, it may be split into small concrete pump, medium concrete pump, and enormous concrete pump. 3. Based on the concrete pump discharge pressure, it may be split into low current, medium current, high current and ultrahigh current.
