density concrete is a mixture that incorporates heavy aggregates, such as iron ore or barite, to increase its density and radiation shielding properties. This type of concrete is used in nuclear facilities, medical facilities, and offshore structures where high mass or protection against radiation is required.
17. No #
Fines Concrete
No #
fines concrete is a mixture that does not contain fine aggregates, allowing voids to form within the matrix. This type of concrete provides good drainage and thermal insulation properties, making it suitable for sub-base layers, green roofs, and lightweight fill applications.
18. Polymer #
Modified Concrete
Polymer #
modified concrete is a mixture that incorporates polymers, such as latex or acrylic, to improve its durability, adhesion, and flexibility.
