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
The invention belongs to civil engineering work energy-saving wall material technology field, specifically a kind of cement maize straw building block.
Background technology
There are a large amount of straw refuses Rural areas, and especially northern country maize straw quantity is very big, deals with very difficultly, conventionally in field, burns serious environment pollution.The materials for wall that farm dwelling is used simultaneously adopts clay solid brick substantially, and not only cost is very high, and fires clay solid brick and need use a large amount of clays, and the contaminate environment that wastes energy is destroyed a large amount of farmlands simultaneously.National departments concerned below, has been forbidden production and the use of clay solid brick for this reason successively in most area.Meanwhile, the cement wall material product of instead of clay solid brick also emerges in multitude out, comprises all kinds of building blocks, wall board, cast-in-situ wall material etc.All kinds of building blocks comprise cement Slag building block, cement figuline building blocks, cement perlite building block, rice straw brick etc.But these building blocks or starting material source is limited, material price is high, need amount transport expense; Complicated construction technique, cannot popularize use in an all-round way.
Summary of the invention
For above walling unit, exist energy consumption large, the shortcoming that cost is high, the farm dwelling that the present invention is north cold area provides a kind of cheap, energy-conserving and environment-protective, mothproof, the durable lasting walling unit of fire prevention, i.e. a kind of cement maize straw building block.Due to the singularity of maize straw, in engineering practice, it is not applied in the materials for walls such as building block as aggregate.A kind of cement maize straw of the present invention building block, adopt ordinary Portland cement and flyash as gelling material, adopt the maize straw of pulverizing as coarse aggregate, adopt rice husk as fine aggregate, add water and fully stir after aftershaping health, be used in one storey house or tier building bearing wall or filled wall.
The technical solution adopted for the present invention to solve the technical problems, is divided into following steps and carries out:
1, maize straw is selected.Select ripe, dry maize straw, remove the positions such as leaf and stamen standby.
2, corn straw smashing.The large I of powder particle diameter is suitably selected according to the performance requriements of building block.General large particle diameter heat insulation effect is better, but supporting capacity is poor; Contrary compared with small particle size, supporting capacity is better, but heat insulation effect is poor.
3, calculate proportioning.Theoretical Calculation and normal concrete are similar, according to the requirement of the particle diameter of maize straw, rice husk particle diameter and bearing capacity of wall body, select suitable proportioning.
4, select suitable admixture.Can increase part slag and natural sand, in order to regulate unit weight and the intensity of building block.
5, can select the most of cement of coal ash instead, to reduce its cost.
6, dry maize straw aggregate need soak in advance, to improve product strength and to save gelling material.
The effect that the present invention is useful is, makes full use of a large amount of maize straw resource in Rural areas, and production unit is simple, invests little, cheap.Adopt the body of wall of this concrete block masonry to reach the unification of load-bearing, insulation, decoration.The building block of a kind of cement maize straw of the present invention has excellent heat-insulating property, load bearing effect and endurance quality.Its material price is cheap simultaneously, construction technology is simple.
Accompanying drawing explanation
Fig. 1 is that maize straw building block is tiltedly built and connect stubble, and Fig. 2 is that maize straw building block is directly built and connect stubble
1. maize straw building block, 2. building block seam mortar, 3. maize straw aggregate, 4. steel tie.
Embodiment
Foundation construction, identical with the common house of unselected clay solid brick wall body structure; Then carry out the construction of reinforcement foundation concrete collar tie beam, on collar tie beam, build maize straw building block 1 by laying bricks or stones, adopt ordinary mortar or polyphenylene granule heat-insulating building block seam mortar 2; Body of wall can stay straight raft or oblique stubble, while keeping somewhere straight stubble, need add steel tie 4; Roofing place, top arranges reinforced concrete circle beam together, and its width is less than thickness of wall body 10cm, adopts inside and outside each 5cm polystyrene board heat-insulatation, thereby avoids collar tie beam cold bridge.Exterior wall adopts Polypropylene Fibers Cement Mortar floated finish, and interior wall adopts polypropylene fibre mixed mortar floated finish.After having plastered, carry out the construction of the decorative engineerings such as coating.
Claims (2)
1. a cement maize straw building block, adopts cement and flyash as gelling material, it is characterized in that coarse aggregate adopts the maize straw aggregate of pulverizing.
2. a kind of cement maize straw building block according to claim 1, is characterized in that maize straw aggregate size can adjust according to supporting capacity and energy-conservation requirement.
