Crack-resistant anti-radiation mass concrete based on waste glass and preparation method thereof

Abstract

The invention discloses crack-resistant anti-radiation mass concrete based on waste glass. The mass concrete comprises the following components: 140-160kg / m<3> of water, 100-300kg / m<3> of cement, 30-100kg / m<3> of a glass powder, 50-180kg / m<3> of fly ash, 800-1100kg / m<3> of fine aggregates, 1400-2000kg / m<3> of coarse aggregates, 0.35-1.9 kg / m<3> of a composite modifier, 2.1-7.8kg / m<3> of a water reducing agent and 0.6-1.2kg / m<3> of fibers, wherein the coarse aggregate is prepared by mixing barite and lead glass; the fine aggregate is prepared by mixing borosilicate glass sand and barite sand. The prepared crack-resistant anti-radiation mass concrete is excellent in working performance, mechanical property, cracking resistance, durability and shielding effects; moreover, the waste glass containing lead, boron and the like can be efficiently recycled, and the crack-resistant anti-radiation mass concrete has obvious economic and environmental benefits.

Description

technical field

[0001] The invention belongs to the field of construction engineering, and in particular relates to a large-volume anti-crack and anti-radiation concrete based on waste glass and a preparation method thereof. Background technique

[0002] Waste glass is an important part of urban solid waste, and waste glass accounts for about 6-11% of the total solid waste in my country. Industrial waste glass can be used for glass reproduction, but daily waste glass is mostly disposed of in landfill due to the impact on product quality during reproduction. The proportion of lead oxide in CRT glass exceeds 20%. Landfilling lead-containing materials can contaminate soil and water sources. The heat-resistant cooker, electric vacuum glass, and waste glass of optical glass are borosilicate glass, which are also in urgent need of high value-added utilization. However, due to its stable chemical properties, waste glass cannot be decomposed by microorganisms. Landfill treatment ...
