摘要

可持续混凝土为世界上日益增长的传统混凝土生产成本提供了一个相当大的解决方案。虽然它通常被描述为便宜,但它的设计和对低收入社区的成本影响需要进行评估。因此,本文评估了可持续混凝土的生产及其在尼日利亚的成本影响。考虑以钢纤维和竹纤维为配筋的高强混凝土的试验设计,目标抗压强度为50 Mpa。钢纤维和竹纤维的比例各为1%。从试验配合比设计和成本分析中,人们意识到钢纤维增强混凝土每立方米最昂贵,成本约为相同体积的普通混凝土的7倍,但竹子是钢作为增强材料的低成本替代品。关键词:经济适用房,竹纤维,混凝土,钢纤维,可持续性

Evaluation of Sustainable Concrete Production and Construction Cost Implication in Nigeria
Sustainable concrete provides a considerable solution to the increasing cost of conventional concrete production in the world. Though, it is generally described as cheap, however it’s design and cost implications for low income communities needs to be evaluated. Hence, this paper evaluates the production of sustainable concrete and its cost implication in Nigeria. Experimental design of high strength concrete made with steel fibre and bamboo fibre as reinforcement having a targeted compressive strength of 50 Mpa was considered. The steel and bamboo fibres were proportioned at 1 % each. From the experimental mix design and cost analysis conducted, it was realized that steel fibre reinforced concrete are most expensive per cubic metre, costing about seven times as much as plain concrete of the same volume, but bamboo is a low cost alternative to steel as a reinforcing material. Key words : affordable housing, bamboo fibre, concrete, steel fibre, sustainability
