Cement clinker dust (CKD) is a problematic waste derived from the cement industry which may cause some problems in clinkering kiln operations and cement performance. CDW has to be discarded despite its hydraulic properties due to high content of chlorine, sulphur and alkalis. Wang et al. (2004) analysed CKD/FA blends activated with NaOH. 50%/50% CKDFA system activated with 2% of NaOH showed ...

The solidifiion and stabilization of calcium carbide residue (CCR) using granulated blast furnace slag was investigated in this study. CCR binding in hydrated slag was explored by Xray diffraction, 29Si and 27Al magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy, and thermodynamic calculations. Mercury intrusion porosimetry and and compressive strength tests assessed ...

Jul 21, 2018· Industries widely use chemicals to manufacture different products like blocks of cement, paints, tiles, furniture, food preservatives, and every little thing. All the products manufactured in industries go through various chemical reactions, such as in the cement industry, sand is mixed with some chemicals so that highquality cement reaches us.
Calcium carbide residue (CCR) is a waste byproduct from acetylene gas production. The main component of CCR is Ca(OH)2, which can react with siliceous materials through pozzolanic reactions, resulting in a product similar to those obtained from the cement hydration process. Thus, it is possible to use CCR as a substitute for Portland cement in concrete.
The cement industry has a long history of safe and efficient use of alternative fuels, ranging from used tires and biomass to a wide variety of secondary and waste materials. An alternative fuel policy provides many benefits to our economy, environment, public health, and energy security. Secondary materials like postindustrial, postcommercial, postconsumer paper, plastic, and other ...
strength is chiefly influenced by w/c (watertocement ratio, mass basis). But, even for a given w/c, substantial variations in concrete strength may be observed based on the characteristics of constituent materials;, cement type, the type of aggregate used, the paste content, mineral and chemical admixtures, etc. [1,2].
