Physico-Mechanical Properties of Bio-Based Bricks

The aim of this work is to improve the high performance of mud bricks. The latter was reinforced with rice straws as stabiliser leading to an improvement of the physico-mechanical properties. Thus, the physical characteristics of the clay such as natural water content, density, atterberg limit, plasticity limit (Wp) and plasticity index (Ip) were determined. Their values are respectively 8.39%, 2025.73 Kg/m3, 47.66%, 29.75% and 17.91%. The clay used is a low plastic organic silt. The normal proctocol provided an optimum dry density (ɣOP) of 1.28 Kg/m3 at an optimum moisture content of 12.42%. The actual density of the straw is 464 Kg/m3, its absorption rate reached 206% in 5 mins and stabilised at 385% at 480 mins of immersion. The maximum bending and compression strengths are respectively 1.52 and 0.164 MPa. The mud brick absorption coefficients obtained are between 4.875 at 0% straw and 20.573% at 3% straw.

介绍了稻草砌块的制作,对草砖房的结构及施工工艺进行了论述。

新型节能稻草砖房热工性能初探

"中央十六届五中全会"做出建设社会主义新农村的决策后,中央对建设社会主义新农村工作进行了全面部署,提出"生产发展、生活宽裕、乡风文明、村容整洁、管理民主"的要求。要实现这个要求,就要首先解决农民的衣食住行问题,改善农民的居住条件更是重中之重。为了解决东北高寒地区农民居住条件问题,从理论上设计了稻草砖房。这种新型住宅是用新型建筑材料稻草砖代替普通红砖来制造房屋,从而改善农民居住条件。为此,从理论上计算稻草砖房的供热负荷,与普通民宅进行对比分析,并得出稻草砖房的上述性能优于普通砖房的结论。
