如砂石不干净(泥含量较大)、砂的细度模数过高或过低等,也会使混凝土强度降低、泌水性增加。
Such as sand not clean (mud high content), sand the fineness modulus too high or too low, also can make the strength of concrete is reduced, and the water increased.
探讨了养护条件、混凝土工作性能、砂率以及砂的细度模数等因素对混凝土早期开裂的影响,并提出了减少、避免开裂的相应措施。
The factors which affect early age cracking were studied such as curing methods, workability, sand ratio and modulus of sand. Corresponding solutions were put forward.
