The influence of the workability of concrete mixture ratio parameters
(1)Water consumption(Water\/cement ratio)  Water is the only liquid substances in concrete system,The liquidity of free water for concrete mixture to provide the source power。In general,The more concrete free free water in the mixture,The smaller the concrete slurry consistency,Rheology, the better。In the concrete free free water is parcel after gelling material surface,The rest of the free water its role to improve the workability of concrete。Free water of many related associated with gelled material consumption,Water in certain conditions,The bigger the dosage of gelled material,The bigger the specific surface area,The more covering the surface of water,Free from the mixture flow role

Concrete crack is related to materials10Big reason
The reason of cracking of concrete structure is very complex,Design、Materials and construction are likely to result in the crack of the concrete engineering。Related to the material of the top ten reasons:  (A)The cement stability is bad  (1)Free free calcium oxide or magnesium oxide are through high heat sintering crystal particles,Curing is slow,In hardened cement after curing,Cause the surrounding cement whetteth phase volume expansion,Make cement craze

Then poly carboxylic acid water reducing agent mildew season how to deal with?
Poly (carboxylic acid water reducing agent as the third generation of high performance water reducing agent,To meet the requirements of different concrete technical performance,With a small amount of retarded components、Bleed air components、Defoaming components、The viscosity of modified components such as distribution of after use。However,High temperature in summer,Join the retarded components(Such as sodium gluconate、Sucrose)The water reducing agent are prone to deterioration,Seriously affect the use effect。How to solve?
