Влияние комплекса химических модификаторов и мелкодисперсного наполнителя на раннюю прочность растворной смеси

The fine filler content, as well as chemical modifiers of BASF influence: polycarboxylatesuperplasticizer type Glenium® ACE 430 and hardening accelerator X-SEED ® 100 on the strength of the mortar-type filler. Studies have found that when added to the mortar mixture of mineral filler, which is a fine-grained quartz sand, water-solid mixing ratio increases, entailing a decrease in strength. With increasing content of superplasticizer 0.27 to 0.4% of the total weight of the solid constituents is observed increase strength. Introduction hardening accelerator X-SEED® 100 mortars modified superplasticizer Glenium ® ACE 430 accelerates the process of hydration of cement in the first hours after mixing (3-6 hours). It was found that the water-cement ratio and Glenium® ACE 430 superplasticize concentration generally show the fine grained concrete with additives used early strength formation features.
