适用于东北地区的一种混凝土配合比的研究

Study on concrete mixing proportion fitting to northeastern region

为了充分利用粉煤灰、矿渣等矿物掺合料,提出一个适用于东北地区的C40混凝土配合比,以力学性能为指标,在常温下进行了抗折和抗压试验,结果表明:当水胶比为0.36,砂率为40%时,单掺粉煤灰等量取代比例为30%的力学性能最佳,适合应用于东北地区。

In order to make full use of fly ash,slag and other mineral admixtures,put forward a suitable for application in the northeast area of C40 concrete with ratio,in mechanical properties as the index,in room temperature resistance strength and compressive test. The results show that when the ratio of water to cement ratio is 0. 36 and the sand ratio is 40%,the mechanical properties of the equivalent replacement ratio of fly ash is 30%,which is suitable for the northeast region.
