Problems solved by technology

[0004] There are two types of coal gangue hollow bricks: load-bearing and non-load-bearing. The load-bearing outer wall needs to be an insulation layer. The effective life of the load-bearing wall is 50 years, while the insulation layer is weathered and peeled off after only 10 years. The load-bearing wall is different from the insulation layer. Longevity; and non-load-bearing walls have very poor thermal insulation and sound insulation effects, and only play the role of partition

preparation example Construction

[0073] The present invention has no special limitation on the preparation method of the corn stalk hollow brick block, and the technical scheme for block preparation well-known to those skilled in the art can be adopted.

[0074] The invention provides a method for preparing corn stalk hollow brick blocks, comprising the following steps:

[0075] Mixing and reacting corn stalks and modifiers to obtain modified corn stalks;

[0076] mixing the modified corn stalks with cement, quick-drying agent and water to obtain block materials;

[0077] The block material is molded, pressed and shaped and demolded to obtain a corn stalk hollow brick block.

[0078] In the present invention, the first choice is the mixed reaction of corn stalks and modifiers to obtain modified corn stalks. The present invention uses the modifying agent described in the above technical solution to modify corn stalks to promote the interaction between corn stalks and cement. The present invention has no spe...

Embodiment 1

[0128] Process 71.25 kg of corn stalks to obtain corn stalk granules with a length of 6 mm to 12 mm and a width of 3 mm to 6 mm, and combine the obtained corn stalk granules with 3.75 kg of modifiers (specify the types of modifiers), 25 kg of Cement (please provide the source of the cement), 1.25kg of quick-drying agent (please provide the specific quick-drying agent and its source) and 12.5kg of water are stirred in a mixer for 5 minutes to obtain block materials;

[0129] Set the parameters of casting and pressing in the automatic casting machine according to the needs, and transport the obtained block material to the automatic casting machine through the conveying and distributing machine for casting and pressing. The pressure is 60kg, and then decompressed, the upper pressure plate rises automatically, the baffles on both sides are separated, the barrier film falls off completely after the sideways, and the bottom plate is moved to the platform, demoulding and marking, and ...

Embodiment 2

[0133] Crush 100kg of corn stalks with a moisture content of <20%, separate and grow into corn stalk particles of 6 mm to 12 mm in width and 3 mm to 6 mm in width, and the obtained corn stalk particles have a mass of 60 kg. Mix the obtained corn stalk particles with 3 kg of modifier , 16.25kg of cement, 1.8kg of quick-drying agent and 8.12kg of water were stirred in a mixer for 10 minutes to obtain block materials;

[0134] Set the parameters of casting and pressing in the automatic casting machine according to the customer's requirements, and transport the obtained block material to the automatic casting machine through the conveying and distributing machine for casting and pressing. The setting pressure is 60kg, and then the pressure is decompressed, the upper side pressure plate is automatically raised, the two side baffles are separated, the barrier film is turned over and completely falls off, the bottom plate is moved to the platform, demoulding, marking, and the masonry ...

Abstract

The invention provides a hollow corn stalk brick building block. The hollow corn stalk brick building block comprises the following raw materials: 50-75wt% of corn stalks, 0.5-5wt% of a modifier, 15-35wt% of cement, 0.1-3wt% of a quick-drying agent and 5-20wt% of water. According to the hollow corn stalk brick building block, the corn stalks are taken as a raw material for preparing a building block, under the action of the modifier, the good interaction exists between each corn stalk and the cement, and a structure can be easily formed, so that the compression resistance and the water invasion property of the obtained hollow building block are improved; the obtained hollow corn stalk building block is applied to wall body buildings, so that a bearing structure, a thermal insulation structure and a maintenance structure of a wall body are completed by one step, the thermal insulation structure and the bearing structure are organically combined into a whole, the service life of the bearing structure and the service life of the thermal insulation structure are the same, and both the bearing and the thermal insulation are considered.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a corn stalk hollow brick block and a preparation method thereof. Background technique [0002] Blocks are man-made blocks made of concrete, industrial waste (slag, fly ash, etc.) or local materials. requirements for institutional reform. [0003] Blocks can be divided into solid blocks and hollow blocks according to their appearance and shape. Hollow blocks have three forms: single row of square holes, single row of round holes and multiple rows of flat holes, among which multiple rows of flat holes are more beneficial to heat preservation. As a new type of wall, the wall composed of hollow blocks alone or with reinforced concrete is widely used in the current construction industry. At present, the materials for building masonry include clay bricks, aerated concrete bricks, slag hollow bricks, coal gangue hollow bricks, cement hollow bricks, etc. Among them, the producti...
