Stalk light body energy-saving heat preserving building blocks and manufacturing method thereof

Abstract

The invention discloses a straw light-weight energy-saving insulated building block and a method for producing the same. The method comprises the following steps: using broken straw segments processed by a surface modifier, high strength low-alkali cement, fly ash, superfine active mixed materials and the like as main raw materials; adding various additives such as a waterproof impermeable agent, a preservative, a high-efficiency water reducing agent, an excitant and the like and modified materials to the main raw materials, mixing all the materials evenly, and adding water to the mixture and blending the mixture evenly; molding, demolding and maintaining the mixture to mold the building block (a reinforcing rib of which the surface is provided with a plurality of transverse lug bosses), and coating cement waterproof fluid on the outside; and making protection layers on two sides of the building block with ordinary Portland cement, sand, slag, additives and water so as to obtain the straw light-weight energy-saving insulated building block. The straw light-weight energy-saving insulated building block has the characteristics of light weight, high strength, good thermal insulation property, low water absorption rate, high freeze-melt resistance, fire prevention, water prevention, seepage prevention, insect and mouse damage prevention and the like, and saves 50 percent of energy for a single wall body material in the northern cold areas. Besides, the straw light-weight energy-saving insulated building block can be widely popularized and applied to the field of construction, in particular to the village and small town dwelling constructions in the northern cold areas.

Description

Technical field: [0001] The invention uses agricultural waste such as straws to manufacture light-weight heat-insulating building materials for northern rural dwellings, and discloses a straw-light, energy-saving, heat-preserving block and a manufacturing method for the block, belonging to the technical field of building energy-saving materials. Background technique: [0002] At present, among the nearly 40 billion square meters of urban and rural buildings in our country, 99% are high-energy buildings, and the annual development trend is 1.5-2 billion square meters. It is estimated that by 2020, the national urban and rural construction area will increase by 30 billion square meters, and the building energy consumption will reach 1.09 billion tons of standard coal. The energy consumption per unit construction area is more than three times that of developed countries. Due to burning coal for heating, the air pollution index in some cities in northern my country is two to fiv...

AI Technical Summary

Problems solved by technology

But the price is expensive, it is difficult to popularize and use in villages and towns houses

In the severe cold area of ​​northern my country, the energy-saving effect of using a single wall material as enclosure and load-bearing wall to reach 50% has not yet been achieved.
