摘要
以水泥、白泥纤维为主要原料,加入分散剂,发泡剂,制备白泥纤维发泡水泥,通过沉降法研究分散剂浓度对白泥纤维分散情况,结果表明:与水泥的质量比范围为0.71%、1.43%、2.14%、2.86%、3.57%、4.29%、5.00%的白泥纤维的最佳分散剂浓度范围为0.80%、0.90%、1.00%、1.10%、1.20%、1.30%、1.40%;研究了白泥纤维掺量对发泡水泥力学性能的影响,结果表明:当分散剂浓度1.30%、白泥纤维4.29%,试样抗压和抗折强度分别达到最大值:0.81MPa、0.34Mpa;研究了空白试样、1.30%分散剂与4.29%白泥纤维试样和4.29%白泥纤维试样的断面泡孔结构,结果表明:1.30%分散剂与4.29%白泥纤维试样泡孔结构均匀.
White mud fibers foaming cement are prepared by adding foam agent H2O2,dispersant to the main raw material for white mud fibers and cement,the effect of concentration of dispersant on white mud fibers dispersibility were studied.by hydrometer method,the optimum dispersant concentration of different dosage white mud fibers,which were 0.71%,1. 43%,2.14%,2.86%,3.57%,4.29%,5.00%compared to the cement mass,were 0.80%,0. 90%,1.00%,1.10%,1.20%,1.30%,1.40%;the effect dosage of white mud fibers on mechanical properties of foamed cement are studied,the results showed the compressive and flexural strength of 4.29% white mud fibers dispersed in concentration for 1.30% reached the maximum value,respectively：0.81MPa,0.34MPa.,bubbles structure of the section for the blank sample,sample of dosage 4.29% white mud fibers dispersed in concentration for 1. 30%,sample of dosage 4.29% white mud fibers are studied,the results showed bubbles structure of sample of dosage 4.29% white mud fibers dispersed in concentration for 1.30% were very uniform.
