SLAKING (HYDRATION) OF LIME CaO + H2O → Ca(OH)2 + Heat CaO is mixed with water in a slaking box until a “putty” has been formed. The putty is then covered with sand to protect it from the action of the air & left for seasoning. Time of seasoning →1 week for mortar use 6...
-Nails in test tube C will get rust because the ordinary water contains dissolved oxygen in it. Then the dissolved oxygen reacts with iron present in nails. Then the nails in test tube C will get rust. Therefore option (C) is correct, Nail C rusts.Note: The mo...

In lab settings, chlorine dioxide is prepared by oxidizing sodium chlorite. This process requires the use of such dangerous chemicals as sulfuric acid. Uses Chlorine dioxide is used in pulp bleaching, flour bleaching and water treatment. It can also be used to disinfect the air and is used in...
water. Alternatively, magnesium hydroxide (Mg(OH)2), which has a high dehydration peak temperature of about 380° C., is strongly alkaline, facilitating decomposition of the synthetic resin, and unstable to acids, and thus had problems, for example, of prohibiting use thereof in an environment...
Foamed glass is widely used in the industry as an insulating material. However, its mechanical properties are not well-investigated yet. Foamed glass is produced from glass waste that causes discrepancy in mechanical properties of the final product. This paper shows a way to increase the limit of...
First, 10 g of the fresh soil sample was weighed, and 90 mL of distilled water was added into a triangular flask with glass beads. The sample was placed in a shaker for 30 min to fully mix the water and soil sample in the triangular flask. Then, 1 mL of the mixed sample was ...
A less porous material is more resistant to deterioration when exposed to groundwater. The variation in the mineralogical composition of the lime used in the manufacture of foundation mortars suggests a deliberate selection of the raw material according to the high-humidity conditions of the foundation...
It was necessary to prepare the bars to determine the volumetric density and water absorption. The granulated foam glass ranged between 5–30%, with a measuring step every 5%. The blocks were also made to determine the thermal conductivity coefficient. In case of these blocks, the filler was ...
