The cement hydration reaction is an exothermic reaction characterised by a rise in temperature within concrete during its setting phase. This is significant in the case of self-compacting concrete (SCC), which has a high cement content and low water–cement ratio. An experimental investigation was undertaken to measure the temperature …

It is often added to soil mixes to improve drainage and to create a more well-draining soil. While both perlite and horticultural sand can be used to improve drainage in soil, they are not interchangeable. Perlite is a more lightweight material and can provide more aeration than sand. Horticultural sand is heavier and can provide more stability ...

Moulding sands with an inorganic geopolymer binder were prepared in a roller mixer. First, sand without additives (without perlite ore and vermiculite) was prepared, which was the reference point. Then, the moulding sands with additives were prepared. The mixing time was 5 min in each case.
