摘要

本研究是基于使用木屑灰作为部分替代材料的水泥在混凝土的性能修改。在混凝土混合料中,分别以5%、10%和15%的木屑灰替代水泥,观察替代效果。木屑灰的使用允许在施工过程中将木屑作为废物进行再利用。由于与水泥相比,锯末灰的重量很轻,混凝土的重量最终会变得更轻。本文设计的混凝土等级为M25,浇筑尺寸为150mm×150mm×150mm的混凝土立方体、尺寸为100mm×100mm×500mm的梁和直径为150mm、高度为300 mm的圆柱体,分别在7天和28天后对其抗压、抗弯和劈裂抗拉强度进行评估。

A STUDY ON THE STRENGTH OF CONCRETE BY PARTIAL CEMENT REPLACEMENT WITH SAWDUST ASH
This study is based on the use of sawdust ash as a partial replacement material for cement in concrete for property modifications. In the concrete mixes, cement was replaced by sawdust ash at 5%, 10%, and 15% by weight, and the effects on replacement were observed. The use of sawdust ash allows the reuse of sawdust as a waste product in the construction process. Due to the lightweight of the sawdust ash in comparison to cement, the concrete ultimately becomes lighter in weight. The grade of concrete designed here was M25 and concrete cubes measuring 150mm×150mm×150mm, beams of sizes 100mm×100mm×500mm and cylinder 150 mm in diameter and 300 mm in height were cast and their compressive, flexural strength, and split tensile strength are evaluated respectively after 7 and 28 days.
