Статья посвящена вопросам изготовления песчано-глиняного кирпича для обеспечения потребностей строительной отрасли Непала в экономичном и экологически чистом мелкоштучном строительном материале. Цель настоящего исследования состояла в подборе оптимальных составов для изготовления песчано-глиняного кирпича с добавлением цемента, который бы обладал достаточной прочностью, малым весом, низкой стоимостью и высоким уровнем экологической безопасности. В настоящей статье рассмотрены варианты составов песчано-глиняных кирпичей при постепенном увеличении доли цементной добавки, вводимой вместо песка и глины, и методика их испытаний для выполнения требований Национальных строительных норм Непала (NBC). При проведении испытаний контролировалось, чтобы водоцементное отношение и другие параметры материалов, используемых для изготовления кирпича, были одинаковыми для всех образцов. Испытаниями было установлено, что по истечение 28 дней прочность на сжатие образцов, в которых доля цемента составляла 15%, незначительно возросла. Испытания 11 образцов с долей цементной добавки от 0 до 50% от объема показали возможность получения песчано-глиняных кирпичей с прочностью на сжатие до 23.44 МПа.

N order to contribute to the sustainability of the brick construction sector, this work studied the formation of economic and environment friendly sandy clay brick. Therefore, the goal was set to be developed, a “sandy clay brick with cement mix”, which has more structural durability, less weight, low cost, together with high performance with respect to indoor air quality. In this research, variation on soil - cement brick with gradual increase in cement content replacing soil material and how the soil- cement brick may be studied using soil and cement as binder by fulfilling the requirement of National Building Code (NBC). The water cement ratio was kept controlled and all other material properties used were same. The effect was seen on compressive strength because the 28 days strength of brick is slightly more when soil is replaced by 15% cement content then no replacement of soil by cement strength. Taking about 11 samples starting from 0 % to 50 % cement content it was found that sandy clay soil - cement brick with compressive strength up to 23.44 MPa with traditional value may be achieved.
