In order to reveal the effect of curing agent ratio variable and age on zinc heavy metal contaminated soil solidified by cement-metakaolin-limestone (LC3) ternary mixture, artificial were used simulate solidification soil. Through a series laboratory tests, change rules unconfined compressive strength electrical conductivity after analyzed. It is found that with increase age, stronger is, lower...

The objective of this work is to obtain a composite clay-cement-metakaolin having good mechanical properties and geotechnical. To do this, lateritic clay from Burkina Faso referenced ALK was characterized by various methods (X-ray diffraction, infrared spectrometry, thermal analysis Inductively Coupled Plasma, Atomic Emission Spectrometry) in order be used as base course after adding cement met...

Coal gangue is used to replace cement clinker prepare cementitious material via activation techniques. Thus, the solid waste can be effectively disposed, and carbon emission from production processes significantly reduced. In this paper, product transformation, reaction mechanism, thermal kinetics of coal were analyzed by X-ray diffraction, analysis, infrared scanning electron microscopy. We em...

Research into the usage of locally available construction material is essential and beneficial in ensuring a cost-effective project. One natural resources that be used as supplementary cementitious metakaolin. This research aims to investigate performance mortar reinforced with micro- ultrafine metakaolin based on compressive strength water absorption tests. Locally sourced was mixed cement aft...

Metakaolin concrete is a kind of porous material, which contains variety chemical ions in the pores. Solutions these pores are exposed to atmosphere and exist evaporation condensation processes, therefore, pore solution volume changes all time. When ion concentration changes, it has an important impact on strength development durability concrete. However, real-time monitoring was difficult. To ...
