摘要

混凝土作为各种结构施工的重要材料,在当前建筑业的发展趋势中有着严峻的需求。骨料占混凝土的主要数量(约70%),其抗压强度和孔隙率等特性受到控制。目前建筑骨料的使用不仅造成了自然资源的枯竭,而且对环境产生了巨大的影响。这项工作的重点是混凝土的强度特性,使用椰子壳作为从椰子加工单元获得的替代材料。根据早期的研究,用椰子壳代替30%的天然粗骨料的标称量已经确定。“乙醇精”被用作矿物外加剂,以不同的比例代替水泥,以补充强度的损失。进行了干密度、湿密度和抗压强度试验。结果表明,30CS A8 (M4)在不影响强度的情况下实现了更低的密度。

Strength Characteristics of Alccofine Based Light Weight Concrete
Concrete being an important material for construction of various structures has severe demand in the present trend of construction industry. Aggregate occupies the major quantity (70% approx.) of concrete based on which characteristics like compressive strength and porosity are controlled. The present usage of aggregate for construction is resulting in the depletion of the natural resources as well as it is showing a great impact on the environment. The work is to focus on the strength characteristics of concrete using coconut shell as an alternative material obtained from coconut processing units. Based on earlier studies a nominal amount of 30% replacement of natural coarse aggregate with coconut shell has been fixed. 'Alccofine' is used as a mineral admixture by replacing cement at various proportions in order to supplement the loss of strength. Tests have been carried out to find out the dry density, wet density and compressive strength. Comparison of the results show that the 30CS A8 (M4) achieving less density without compromising the strength.
