Abstract

The invention discloses lightweight high-strength concrete and a preparation method thereof. The lightweight high-strength concrete comprises the following components by weight: 550-650 parts of Portland cement, 120-150 parts of pumice stone, 100-150 parts of expanded perlite, 90-110 parts of fly ash, 75-80 parts of glass beads, 10-25 parts of methyl silicone oil and 110-130 parts of water. The lightweight high-strength concrete has the beneficial effect of high structural strength.

Description

technical field [0001] The invention relates to concrete, in particular to a lightweight high-strength concrete and a preparation method thereof. Background technique [0002] Lightweight concrete has been studied for many years at home and abroad, but the highest strength of lightweight concrete has been maintained below 70 MPa, and the bulk density is basically close to 2000kg / m3. Because lightweight concrete has the characteristics of light weight, good thermal insulation and sound insulation effects, lightweight concrete is widely used in modern energy-saving buildings. However, due to the development of modern urbanization, the bearing capacity required by concrete buildings is getting higher and higher, and the application of lightweight concrete in many high-strength prefabricated buildings is still greatly limited. [0003] The Chinese patent whose publication number is CN103396064A discloses a kind of green environmental protection lightweight high-strength powder ...
