Masonry cements are used primarily for mortar. They consist of a mixture of portland cement and ground limestone or other filler together with an air-entraining agent or a water-repellent additive. Waterproof cement is the name given to a portland cement to which a water-repellent agent has been added.
"For sand-cement-type-based products the main problem is the mixing. In Bangladesh there is not a proper standard as of yet, they use cheap machines where the mixing is by hand… That's why we have proposed mechanisation of the process from the mixing to the compression." CSEB blocks that contain more than 20% sand can crack, …
The cement industry is a major contributor to carbon emissions, responsible for 5–8% of global emissions. This industry is expanding, particularly in emerging economies, and it is expected that CO2 emissions will rise by 4% by 2050. To address this critical concern, this paper identifies ten factors that contribute to carbon emissions in the …
