Review on the Preparation of Grout from Quartz Sand

Cementitious grout is a paste made of cementitious materials, mineral admixtures, admixtures and water mixed in a certain ratio, which is widely used in construction projects. Due to its good physical and chemical properties, grout is now also playing great potential in the industrial field. As grout is often used in areas with high strength requirements such as repair and reinforcement of concrete, installation of large equipment, and grouting, the particle packing density has a great impact on its performance, so how to improve the particle packing density to enhance its strength is particularly important.
