摘要
通过将磨细的废砖粉取代水泥制作胶砂试件,并测其抗折、抗压强度值来研究废砖粉的潜在活性,并在此基础上,进一步研究了石灰对废砖粉活性的激发作用。结果表明:磨细的废砖粉具有潜在活性,且粒径越小,活性越大;在一定掺量时,石灰可进一步激发废砖粉的活性。
In the paper, grinding waste brick powder was used to replace parts of cement in different substitutive percent in mortar, and by testing the flexural and compressive strength, the potential activity of waste brick powder was researched. On this basis, the activated effect of lime on the waste brick powder was further researched. The result showed that the grinding waste brick has potential activity, and the smaller the particle size is, the greater the activity is; the potential activity of.waste brick powder could be. further activated, while the lime was added in a certain dosage.
