a lightweight concrete

Abstract

The invention discloses a light-weight concrete. The components of the raw materials are calculated in parts by weight, including 100 parts of cement, 50 parts of water, PC? 60-70 parts, quicklime 10-15 parts, carbon powder 5-7 parts, calcium carbonate 1-4 parts, zinc sulfate 0.05-0.2 parts. This invention breaks the formula of traditional concrete, replaces part of cement with PC, activates calcium carbonate and zinc sulfate, and reinforces with quicklime. Concrete needs to be reduced by more than 10 times, which greatly reduces the burden on construction.

Description

technical field

[0001] The present invention relates to a concrete. Background technique

[0002] Concrete, referred to as "concrete (tóng)": refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. Generally speaking, the term concrete refers to cement as cementing material, sand and stone as aggregate; mixed with water (with or without admixtures and admixtures) in a certain proportion, and obtained by stirring, molding and curing. Cement concrete, also known as ordinary concrete, is widely used in civil engineering. However, the existing concrete imposes a strong burden on construction due to its heavy weight.
