Cementation (geology) A brief, easy-to-understand description of cementation is that minerals bond grains of sediment together by growing around them. This process is called cementation and is a part of the rock cycle. Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary ...
Deep cement mixing consists of using specially designed equipment, such as augers or mixing paddles, to mechanically mix the soil with an in-situ binder. The process simultaneously breaks up the soil without removing it, injects a binder at low pressure and thoroughly mixes the binder with the soil to form a reinforced block of soil after ...
