Aiming at the question of improvement expansive soil in Nanyang area, composite method lignin and cement was adopted. Based on unconfined compressive strength test, variation law improved with different content, compaction degree curing age studied. The test results show that can effectively improve soil. L-C (lignin cement) reaches maximum when content is fixed 4% 1%. increases increase age, g...

According to the masonry standard the compressive strength is basically dependent on factors such as the mortar strength and the relative values of unit and mortar strength. However interlocking brick has none or less use of mortar. Therefore there is a need to investigate the behavior of masonry walls using interlocking bricks. In this study a series of tests have been conducted; physical prop...

Abstract Peat soil is one of the types available in Malaysia, which has a high compressibility and low shear strength. Thus, peat considered inappropriate to support construction site its natural state. Among methods suitable for stabilization using cement. However, quantity cement required quite large made this method not too environmentally friendly due carbon dioxide, CO 2 emission from prod...

In spite of soil treatment using Portland cement being well documented, it is hard to find all the contents related this topic in one document. This paper aims provide information inventory about chemical and mechanical changes that take place properties, alteration engineering characteristics which occur - mixtures. The mechanism over time documented as well. Some conflicted results were detec...
