| 摘 要： | 本文对净浆(?)骨料工艺在掺粉煤灰混凝土(简称粉煤灰混凝土)中的增强效果进行了研究.试验表明对硅酸盐水泥、普通硅酸盐水泥的粉煤灰混凝土,采用净浆(?)骨料工艺后,其各龄期强度都显著提高,对不同的粗骨料品种,工艺效果都较好,微(?)研究表明,净浆(?)骨料工艺减少了自由水分向界面的集中,提高了界面区密实度,从而使混凝土的强度得到提高.

| Abstract: | The strengthening effect of AEP (Aggregate Enveloped in Cement Paste) technology used in the concrete blended wity fly ash was studied.
The data showed that by using AEP mixing technology .the compressive strength of both fly ash concrete of Portland and ordinary Portland cement could be obviously increased at every age. AEP technology was suitable for various kinds of coarse aggregate.
Microscopic analysis indicated that by using AEP technology, the free water which moved to the under-surface of the coarse aggregate could be reduced and the density in interfacial zone could be increased. Thus,the strength of concrete could be increased. |
