在混凝土生产中利用废料为一些环境问题和与废料管理有关的问题提供了令人满意的解决方案。以稻壳灰、麦草灰、榛子壳灰、甘蔗渣灰等农业废弃物为原料，研制了掺合水泥。关于甘蔗渣灰（BA）作为水泥砂浆部分替代材料的研究报道很少。研究了BA部分替代水泥对硬化混凝土物理力学性能的影响。研究混凝土的性能包括抗压强度、劈裂抗拉强度、吸水率、渗透特性、氯离子扩散和抗氯离子渗透。试验结果表明，BA是一种有效的矿物掺合料，其最佳水泥取代率为20%。(c)2007爱思唯尔有限公司保留所有权利。
The utilization of waste materials in concrete manufacture provides a satisfactory solution to some of the environmental concerns and problems associated with waste management. Agro wastes such as rice husk ash, wheat straw ash, hazel nutshell and sugarcane bagasse ash are used as pozzolanic materials for the development of blended cements. Few studies have been reported on the use of bagasse ash (BA) as partial cement replacement material in respect of cement mortars. In this study, the effects of BA content as partial replacement of cement on physical and mechanical properties of hardened concrete are reported. The properties of concrete investigated include compressive strength, splitting tensile strength, water absorption, permeability characteristics, chloride diffusion and resistance to chloride ion penetration. The test results indicate that BA is an effective mineral admixture, with 20% as optimal replacement ratio of cement. (c) 2007 Elsevier Ltd. All rights reserved.
