摘要

混凝土是应用最广泛的建筑材料。在世界范围内,高层建筑都是采用高强混凝土模式建造的。对建筑材料日益增长的需求要求在生产传统混凝土时使用替代材料。现在一天的细骨料来源由于消耗高而减少,所以需要一些材料来替代砂石。本工作的目的是研究混凝土的强度和耐久性。在混凝土配合比设计中,采用m70级混凝土,含铜渣混凝土部分替代细骨料,含矿物外加剂部分替代水泥。铜渣掺量为40%替代细骨料,硅灰掺量为5%、10%、15%和20%,GGBS掺量为5%、10%、15%和20%替代水泥,进行了强度试验和耐久性试验。试验结果表明,用40%的细骨料代替铜渣可以提高铜渣的强度。硅粉和GGBS作为水泥的部分替代品(可达15%)。结果表明,在混凝土中掺入铜渣和矿物掺合料,与普通混凝土相比,强度有明显提高,成本有明显降低。

Experimental Study on Strength and Durability Properties of High Strength Concrete Using Mineral Admixtures and Copper Slag
: Concrete is the most widely used building material. In worldwide the high rise buildings are constructed by using high strength concrete mode only. Growing demand for construction materials necessitated the usage of alternative materials in the production of conventional concrete. Now a day’s fine aggregate source is reduced due to high consumption, so some material is needed to replacing of sand. The objective of this work is to study the strength and durability properties of concrete. Here M 70 grade concrete used and concrete containing copper slag as partial replacement of fine aggregate and mineral admixture as partial replacement of cement in the concrete mix design. Copper slag content has been 40% as a replacement of fine aggregate and silica fume 5%,10%,15% & 20% and GGBS 5%,10%,15% & 20% as a replacement of cement respectively .This research paper study on strength test& Durability test. The test results show 40% replacement of fine aggregate as copper slag gives them more strength. And Silica fume & GGBS as partial replacement of cement (up to 15%). From the results, it was observed that the use of copper slag and mineral admixture in concrete has shown a considerable increase in strength and reduction of the cost when compared with normal concrete.
