sea sand concrete additives

Application of sea sand for 3D concrete printing - IOPscience

The paper shows the promising use of sea sand for additive technologies in construction. The use of sea sand reduces the setting time of the concrete mix and increases the initial strength compared to conventional quarry construction sand. A comparative analysis of the characteristics of sea and quarry sands was performed.

Sand, Cement Additives Pentagon, Jersey

Cement is a hydraulic bonding agent which is obtained by heating, then grinding, a mixture of limestone and clay. Most cements are made from clinker and additives and are usually used in the form of a powder. Cement sets when mixed with water. Combined with sand and chippings, it turns into rock-hard concrete or mortar.
