The study on the influence of early age damage concrete its long-term strength development is great importance. In this work, 102 cubes with and without supplementary cementitious materials (SCMs) were prepared. pre-loading loading degrees 20%, 50%, 80% corresponding compressive at 3-, 7-, 14-, 28 d was applied to samples. Then, samples further cured 270 d, tested by uniaxial compression test. ...

The need to produce more sustainable concrete is proving imminent given the rising environmental concerns facing industry. Blended cement concrete, based on any of prominent supplementary cementitious materials (SCMs) such as fly ash, ground granulated blast-furnace slag, silica fume, calcined clay and limestone powder, have proven be best candidates for mixes. However, a reliable sustainabilit...

The use of clays as resource supplementary cementitious materials (SCMs) for a new generation low-carbon cements and concretes is currently the subject intense research efforts. To this purpose, large number clay resources have been explored, characterized evaluated. This paper introduces basic knowledge concepts on occurrence mineralogy, before presenting up-to-date properties suitable SCMs. O...

The autogenous healing potential of cement-based materials is affected by multiple factors, such as mix composition, crack width, pre-cracking age and external environmental conditions. In this study, the effects curing conditions supplementary cementitious (SCMs) on self-healing early cracks in cement mortar were investigated. Three conditions, i.e., standard curing, wet–dry cycles incubated w...

The RILEM AAR-12 concrete prism test is a performance method for testing aggregate combinations together with various binder (i.e. composite cements or pure Portland + Supplementary Cementitious Materials; SCMs). This essentially the same as AAR-11, except that storage conditions were modified to evaluate aggregates and compositions road pavements on Federal highways avoid ASR damage, especiall...

Bentonite is a mixture of clay and non-clay minerals. Montmorillonite mineral dominant in bentonite. Silica alumina bond the crystal structure montmorillonite. Therefore, they cannot contribute to pozzolanic reaction. Heat treatment bentonite leads destruction montmorillonite converting silica reactive phases. Thermally activated (TAB) relatively low pozzolan when used as partial replacement Po...

This letter describes a newly discovered phenomenon: ductile fracture in cementitious materials. The brittle nature of materials such as concrete and ceramics has prompted the development of various approaches to enhance their fracture toughness. Fibre reinforcement has been the common focus in the toughening of the brittle materials. Two types of fracture have been observed to date in cementit...
