Embodiment Construction

[0014] The foundation construction is the same as that of ordinary houses with ordinary clay solid brick wall structure; then the basic reinforced concrete ring beam construction is carried out, and corn straw blocks 1 are built on the ring beam, and ordinary mortar or polystyrene particle insulation block joint mortar 2 is used The wall can be left with straight stubble or slanted stubble, and when the straight stubble is left, it is necessary to add tie bars 4; a reinforced concrete ring beam is set on the upper roof, and its width is 10cm less than the thickness of the wall. Thereby avoiding ring girder cold bridges. The exterior wall is finished with polypropylene fiber cement mortar, and the interior wall is finished with polypropylene fiber mixed mortar. After the plastering is completed, the construction of decoration works such as paint is carried out.

Abstract

Aiming at the defects of high energy consumption and high manufacturing cost, the invention provides a low-cost, energy-saving and environment-friendly, fire-proof and mothproof and durable wall building block, namely a cement-maize straw building block, for rural houses in cold areas in the North. According to the invention, ordinary portland cement and coal ash serving as cementing materials, crushed maize straws serving as coarse aggregate and rice husks serving as fine aggregate are mixed with water and stirred sufficiently to be formed, and then the formed product is cured to obtain the cement-maize straw building block; and the cement-maize straw building block can be used in a bearing wall body or a filled wall body of a single-layer house or a multi-layer house. The wall body built of the building blocks has excellent thermal insulation performance, bearing effect and durability. In addition, the materials of the cement and maize straw building block is low and the construction process is simple.

Description

technical field [0001] The invention belongs to the technical field of civil engineering energy-saving wall materials, in particular to a cement corn stalk block. Background technique [0002] There is a large amount of straw waste in rural areas, especially the large amount of corn straw in northern rural areas, which is very difficult to deal with. It is usually burned in the field, which seriously pollutes the environment. At the same time, the wall materials used in rural housing basically adopt clay solid bricks, which are not only expensive, but also need a large amount of clay to burn clay solid bricks, which wastes energy and pollutes the environment, and destroys a large amount of farmland. For this reason, the relevant state departments have successively banned the production and use of clay solid bricks in most areas. At the same time, a large number of cement wall material products that replace clay solid bricks have emerged, including various blocks, wall panel...
