养护温度对矿粉水泥石强度及细观结构影响研究
Effect of Curing Temperature on the Strength and Microstructure of Slag Cement Block
摘要
Abstract
In order to study the early (28 d) strength and distribution of pore microstructure characteristics of slag cement block under different curing temperature , the water cement ratio of the cement block was 0.24, doped with different amounts of slag as admixture to the cement block , the cement blocks were maintained at minus three degrees Celsius and twenty degrees Celsius for twenty -eight days respectively , measure the compressive strength of cement block , analysis of the early pore structure of cement block by using the pore structure analyzer , then through the pore structure of cement block calculate the actual strength of cement blocke , comparative analysis of its law .The results show that:at the same amount of slag, the early compressive strength of the cement blocks at minus three degrees Celsius curing temperature is decreased significantly than at twenty degrees Celsius curing temperature , hardened cement air containing volume becomes small , the bubbles spacing factor and average pore chord length increase, pore coarsening seriously;With the increase of slag amount , the early compressive strength of cement block is decreased , hardened cement air containing volume increases , the bubbles spacing factor and average pore chord length increase ,the bubbles spacing factor , average pore chord length and early compressive strength of cement blocks at minus three degrees Celsius curing temperature change trend is more obviously than at twenty degrees Celsius .关键词
