Abstract

The rise in paper waste from the paper processing sector is becoming the most important issue of disposal by filling large space and polluting the atmosphere, as it rises day to day. To decrease the paper waste as well as environmental emissions, it is recommended to use the paper waste in concrete as Hypo sludge. That contains the properties of cement such as SiO2 & Mg. Cement is the predominant material in concrete. In this research cement is replaced with fly ash as well as hypo sludge. By adding 5percent of fly ash and 0%, 3 %, 6%,9%,12% and 15% of hypo sludge, split tensile strength & compressive strength of concrete as well as Hypo sludge concrete efficiency are being tested. Split tensile strength & compressive strength of hypo sludge concrete are improved by the experiment up to 9% behind this % strength will decrease. In this journal the extension of research work is added that is flexural strength of concrete adding fly ash & hypo sludge in concrete and durability of concrete are studied. Performance of hypo sludge concrete, result and optimum percentage are mentioned in this paper.

低污泥与粉煤灰掺合物对混凝土性能的影响

纸张加工部门产生的纸张废物日益增多，填满了大量空间，污染了大气，正成为处置的最重要问题。为了减少纸废料和环境排放，建议将混凝土中的纸废料用作Hypo污泥。它含有水泥的特性，如SiO2和Mg。水泥是混凝土的主要材料。在本研究中，水泥被粉煤灰和劣质污泥代替。通过添加5%的粉煤灰和0%、3%、6%、9%、12%、15%的低浓度污泥，测试了混凝土的劈裂抗拉强度、抗压强度以及低浓度污泥混凝土的效率。实验结果表明，低污泥混凝土的劈裂抗拉强度和抗压强度均有提高，达到9%后强度将下降。本文对研究工作进行了延伸，研究了混凝土中掺入粉煤灰和低浓度污泥对混凝土抗弯强度的影响以及混凝土的耐久性。本文介绍了低污泥混凝土的性能、效果和最佳掺量。
