Thick,the fine aggregate dividing line size and the maximum particle size will be generally thick,the fine aggregate dividing line size to decide as 4.75mm,namely belongs to the fine aggregate through the 4.75mm mesh's stone material,the 4.75mm above stone material belongs to the coarse aggregate,in the coarse aggregate maximum particle size reference present standard gradation scope takes 26.5mm.
The semi-rigid basic unit's intensity and the rigidity along with the stadium change,along with the stadium growth,the intensity and the rigidity can grow,but the different material grows the scope is different,the identical material is also different in the different area's growth rate,moreover the binding dosage is bigger,the stadium influence is also bigger.
The air shrinkage characteristic,the volume contraction influencing factor is as follows:Fine grain content and mineral component earth plasticity index cement dosage blend water content detection time and water loss aggregate average grain diameter.Domestic and foreign to inorganic binding air shrinkage performance research,uses the air shrinkage strain and the coefficient of shrinkage two target attributes mostly.Carries on the appraisal once in a while according to the air shrinkage strain and coefficient of shrinkage's size by prompt the water loss relations to its road with the performance.
