Desiccation shrinkage is a key factor contributing to the engineering hazards in expansive soil. To inhibit initiation and expansion of cracks, composite improvement approach using biochar sisal fibers was applied soil from Nanning, Guangxi. An orthogonal test method employed conduct desiccation cracking tests on improved soil, investigating effects crack length, ratio width. The results indica...

This study investigates the deformation of free and stress restrained alkali-activated slag concrete (AASC), respectively, under semi-adiabatic condition. The shows first thermal expansion, which is compensated soon by autogenous shrinkage. subsequent cooling down aggravates shrinkage development tensile stress, eventually results in early cracking concrete. show that condition severer for AASC...

Excessive cracking due to restraint of thermal and shrinkage strains is a widespread problem in the concrete construction industry. In design, induced managed by provision reinforcement intended distribute internal such way as control pattern limit crack widths. The area secondary (horizontal) required members retaining walls water tanks often governed need early age cracking. This paper presen...
