Owing to their lower carbon footprint and efficient performance compared portland cement (PC), alkali-activated binders (AAB) show promising potential as an alternative PC. The present paper investigates the high-temperature of AAB concrete through compressive bond strength tests. Four different mixes with varying proportions fly ash: slag (100:0, 70:30, 60:40, 50:50) cured under ambient condit...

Contamination of heavy metals has been a serious environmental problem due to increasing anthropogenic activities such as mining, smelting, livestock, landfills, waste dumps, and agriculture. Bioleaching experiments were conducted using native Bacillus cereus MAMPE19 BCG, isolated characterized from previous research, test removal arsenic (As) actual mining waste. Mineralogical characterization...

Desirable scaffolds for tissue engineering should be biodegradable carriers to supply suitable microenvironments mimicked the extracellular matrices for desired cellular interactions and to provide supports for the formation of new tissues. In this work, a kind of slightly soluble bioactive ceramic akermanite (AKT) powders were aboratively selected and introduced in the PLGA matrix, a novel l-l...

This study produced ceramics powder derived from the CaO-MgO-Al2O3-SiO2 system using mechanical wet milling and cold pressing method. The time was changed between 30 min to 2 h sintered at 950 ⁰C for 1 h. pellet performed via in ambient temperature pressure of 5 tonnes. effect on linear shrinkage, density, porosity compressive strength were investigated. X-ray diffraction results demonstrated t...

In order to develop fire resistant geopolymer materials, it is necessary understand the parameters controlling their thermal behavior such as content of alkali or rare earth cations. This study highlights effect carbonate nature and amount on geopolymers in propose a model behaviour predict shrinkage. For this, various mixtures kaolin calcite and/or dolomite with different percentages were calc...
