Anti-seismic wall material and method for preparing same

Abstract

The invention discloses an anti-seismic wall material and a method for preparing the same. The anti-seismic wall material in a formula comprises, by weight, 5-30 parts of cement, 5-20 parts of lime, 50-70 parts of fly ash, 0.5-5 parts of gypsum, 5-25 parts of regenerated rubber powder and an appropriate amount of water. The method includes digesting the lime; weighing the components, pouring raw materials into a stirrer, stirring the raw materials under a dry condition for 2 minutes, then adding the appropriate amount of water into the stirrer and stirring the raw materials again for 3-5 minutes to obtain mixtures; pouring the stirred mixtures into brick molds or building block molds and vibrating and molding the stirred mixtures for 1-2 minutes; maintaining the mixtures for a day at the temperature of 20-30 DEG C under the condition of humidity higher than 50%, or delaying curing of the mixtures for 1 hour, then maintaining the mixtures in wet steam at the temperature of approximately 90 DEG C for 6-8 hours, and removing the mixtures from the molds to obtain bricks or building blocks; maintaining the bricks or the building blocks in high-temperature and high-pressure saturated steam at the temperature of 150-180 DEG C for 7-12 hours to obtain finished products. The anti-seismic wall material has the advantages of light weight, low elastic modulus, good elasticity, excellent toughness and ductility, high ratio of bending-compressive strength, heat insulation and the like.

Description

technical field [0001] The invention relates to an anti-shock and anti-shock wall material and a preparation method, belonging to the field of building materials. Background technique [0002] Since the reform and opening up, with the development of China's economy, people's living standards have been greatly improved, and my country's automobile industry has developed rapidly, followed by a gradual increase in waste rubber tires, and at the same time, the waste of other rubber industrial products is also increasing. The amount of waste rubber occupies the first place in the world. Waste rubber products have a network structure, are not easy to degrade under natural conditions, are insoluble in water, difficult to dissolve in organic solvents, and are not easy to rot. [0003] At present, the treatment and disposal methods of waste rubber mainly include landfill, accumulation, thermal decomposition, fuel, production of reclaimed rubber and tire retreading. Because waste rub...

Problems solved by technology

At present, the most widely used building materials are often cement concrete and ordinary wall materials. Most of these building materials are brittle materials with poor seismic performance and need to be modified.

Studies have shown that autoclaved aerated concrete has certain seismic performance, but its strength is low, the distribution of pores and the size of pores are not uniform, and the ability to resist earthquakes is limited.
