Unfired admixed soil blocks are made up of soil plus stabilizers such as binders, fibers, or a combination of both. Soil is abundant on Earth, and it has been used to provide shelter to millions of people. The manufacturing and usage of cement and cement blocks raise several environmental and economic challenges. Due to disposal issues, agricultural and industrial waste is currently the biggest hazard to the environment and humanity in the world. Consequently, environmental degradation brought on by agricultural waste harms the ecology. As a result, researchers are attempting to develop an alternative to cement blocks, and various tests on unfired admixed soil blocks have been done. This investigation uses agricultural waste (i.e., paddy straw fiber and sugarcane bagasse ash) and industrial waste (i.e., marble dust) in manufacturing unfired admixed soil blocks. Under this investigation, the applicability of unfired soil blocks admixed with marble dust, paddy straw fiber, and bagasse ash was studied. The marble dust level ranged from 25% to 35%, bagasse ash content ranged from 7.5% to 12.5%, and the content of paddy straw fiber ranged from 0.8% to 1.2% by soil dry weight. Various tests were conducted on the 81 mix designs of the prepared unfired admixed soil blocks to find out the physical properties of the block followed by modeling and optimization. The findings demonstrate that the suggested method is a superior alternative to burned bricks for improving the physical properties of admixed soil blocks without firing.
免烧混合土砌块由土壤加粘结剂、纤维等稳定剂或两者的组合制成。地球上土壤资源丰富，已被用于为数百万人提供住所。水泥和水泥砌块的生产和使用带来了若干环境和经济挑战。由于处置问题，农业和工业废物目前是世界上对环境和人类最大的危害。因此，农业废物造成的环境退化损害了生态。结果，研究人员正试图开发一种替代水泥砌块的材料，并已对免烧混合土砌块进行了各种测试。本研究在制造免烧混合土砌块时使用了农业废物（即稻草纤维和甘蔗渣灰）和工业废物（即大理石粉尘）。在本研究中，研究了掺有大理石粉尘、稻草纤维和甘蔗渣灰的免烧土砌块的适用性。大理石粉尘含量为土壤干重的25%至35%，甘蔗渣灰含量为7.5%至12.5%，稻草纤维含量为0.8%至1.2%。对制备的免烧混合土砌块的81种配合比设计进行了各种测试，以找出砌块的物理性能，随后进行建模和优化。研究结果表明，所建议的方法是一种优于烧制砖的替代方法，可在不烧制的情况下改善混合土砌块的物理性能。
