1) aggregate pre-wetting
骨料预湿
1.
Through experiments of water permeability of lightweight aggre-gate concrete(LWAC)with different mix proportion,the effects of water to cement ratio(W/C),compressive strength,air content and aggregate pre-wetting time on the LWAC permeability were studied.
试验结果表明:①轻骨料混凝土水灰比越小或抗压强度越高,其渗透系数就越小,抗渗性也就越好;②含气量小的轻骨料混凝土抗渗性优于含气量大的,但是当水灰比较小时,含气量对渗透系数的影响将减弱;③骨料预湿存在最佳预湿时间。
2) pre-placed aggregate
预填骨料
1.
The influence of bentonite on the performances of the pre-placed aggregate concrete is studied based on the special structure of bentonite.
基于膨润土的特殊结构,研究了膨润土对预填骨料混凝土各方面性能的影响。
3) precooling of aggregates
骨料预冷
4) saturated lightweight aggregate
预湿轻集料
1.
Effect of early autogenous shrinkage in high-strength concrete by using saturated lightweight aggregates;
预湿轻集料对高强混凝土早期收缩的影响
6) water contained in aggregates
骨料的自然湿度
补充资料：骨料
分子式：
CAS号：
性质：混凝土、砂浆和化学灌浆材料中起骨架和填充作用的粒状材料。如砂、砾石、碎石等。有时也将胶黏剂中的颗粒状填充料称为骨料。
