A new type of composite block

Abstract

The invention discloses a novel composite block. Based on the original traditional block, a groove which is 10mm in width and 1.5mm in depth is arranged on the surface of the composite block to strengthen the binding force between the block and the mortar, prevent the mortar from falling effectively and improve the shear capacity, so as to enhance the ability to withstand natural disasters of block buildings. By certain holes formed in the block, the block has better temperature reduction and energy saving performances to meet the energy saving requirement of buildings as thermal conductivity and heat transfer coefficient are reduced. Compared with traditional blocks, the novel composite block is identical in performances with the traditional one. Moreover, the raw materials of the novel composite sintered block mainly include coal refuse, construction waste, coal ash, furnace slag, mineral residue and sludge which all are from construction and industrial wastes, therefore, the difficulty in handling construction sludge and wastes is overcome, the problem of environment pollution caused by solid wastes is solved, the cultivated land is protected, and the solid wastes are recycled. In the engineering application, the block has good social, economical, and environmental benefits.

Description

technical field [0001] The invention relates to a method for making a novel composite sintered block, in particular to a formula for making sintered blocks suitable for coal gangue, fly ash, silt, and construction waste, and belongs to the technical field of civil engineering and building materials. Background technique [0002] In recent years, with the continuous improvement of my country's building energy-saving design standards, it has become a pursuit to seek new energy-saving exterior wall enclosure structures, and many new wall materials have emerged as the times require. From the cost performance analysis of energy-saving walls, composite thermal insulation wall materials still have great advantages, especially thermal insulation materials and exterior decorative surface materials can have the same durability (including weather resistance) as the main structure, and their service life is longer than that of other energy-saving walls. unattainable. At present, althou...

AI Technical Summary

Problems solved by technology

At present, although there are related patent reports on the cohesive composite thermal insulation blocks at home and abroad, the above-mentioned patents are based on the protection of the block type, such as the hole arrangement, hole size, hole shape, and the difference in the type of tenon or dovetail groove.

However, there is a lack of systematic research on the specific thermal insulation effect, mechanical properties and wall materials used.

Although some literature has carried out experimental analysis on a certain type of block, it is impossible to optimize the actual engineering application of these blocks and lack of reports on related design methods, so it is difficult to promote the application and form industrial production
