Embodiment 1

[0015] (1) Material selection: Weigh 35 kg of ceramsite, 8 kg of cement, 16 kg of medium sand, and 1 kg of water reducing agent in proportion;

[0016] (2) Stirring: put the ingredients weighed in proportion into a mixer, add water and stir for 2-3 minutes;

[0017] (3) Production: place a steel wire mesh sheet at the bottom of the mold, put the mixed concrete into the mold, vibrate with a flat vibrator to vibrate the concrete slurry, then place a steel wire mesh sheet on the top of the mold, and continue to use a flat plate The vibrator vibrates to make it smooth;

[0018] (4) Demolding: According to the ambient temperature, the cement specifications selected for construction and the demoulding operating procedures, master the appropriate demoulding time for demoulding. At 0-15 degrees, aluminate quick-hardening cement is used for construction, and the demoulding time is 2-3 hours; at 15-20 degrees, high-quality early-strength cement is used for construction, and the demould...

Abstract

The invention provides preparation for a concrete ceramsite wallboard. The concrete ceramsite wallboard is characterized by being prepared through the following steps: (1) material selection: a step of weighing materials according to a proportion; (2) stirring: a step of placing the materials weighed in proportion into a stirrer, adding water, and carrying out stirring for 2 to 3 minutes; (3) manufacturing: a step of placing a steel wire mesh at the bottom part of a mould, pouring stirred concrete into the mould, carrying out vibration treatment by using a plate vibrator until a cement paste of concrete is vibrated out, then placing a steel wire mesh onto the mould, continuing performing vibration by using the plate vibrator, and carrying out levelling; and (4) demoulding: a step of controlling the proper time of demoulding, and carrying out demoulding according to environment temperature and demoulding operation regulations. The concrete ceramsite wallboard provided by the invention solves the problems on high water absorption rate, easy aging, easy cracking and deformation of partition boards like plant fiber reinforced boards, and is applicable to being used as a non-load bearing partition board in construction.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a lightweight concrete partition wall board using ceramsite as an aggregate. Background technique [0002] At present, the non-load-bearing partition boards widely used in construction mainly include plant fiber reinforced boards, steamed cement boards, slag fly ash boards, fly ash gravel cement boards, gypsum boards, etc. The plant fiber reinforced board is made of chemical raw materials and ingredients, which is easy to age, crack, and has a short life. Ceramic tiles and stones are easy to crack and fall off, and cannot be nailed, drilled, or threaded horizontally or vertically; slag fly ash boards and fly ash gravel cement boards have high water absorption and are easy to crack. The overall structural strength is low, and the impact resistance and bending load resistance are low. ; Gypsum board has a strong water absorption rate, and contact with water will cause gypsum to d...
