Embodiment 1

[0015] (1) Material selection: Weigh 35kg of ceramsite, 12kg of cement, 12kg of slag, and 1kg 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 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 mesh sheet on the top of the mold, and continue to use a flat plate The vibrator vibrates to make it smooth;

[0018] (4) Demoulding: 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 demoulding time is 3-4 hou...

Embodiment 2

[0020] (1) Material selection: Weigh 39.5g of ceramsite, 11kg of cement, 9kg of slag, and 0.5kg of water reducing agent in proportion;

[0021] (2) Stirring: put the ingredients weighed in proportion into a mixer, add water and stir for 2-3 minutes;

[0022] (3) Production: Place a steel 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 mesh sheet on the top of the mold, and continue to use a flat plate The vibrator vibrates to make it smooth;

[0023] (4) Demoulding: 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 demoulding time is 3-4 h...

Embodiment 3

[0025] (1) Material selection: weighing in proportion: ceramsite 45g, cement 8.3kg, slag 6kg, water reducing agent 0.7kg;

[0026] (2) Stirring: put the ingredients weighed in proportion into a mixer, add water and stir for 2-3 minutes;

[0027] (3) Production: Place a steel 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 mesh sheet on the top of the mold, and continue to use a flat plate The vibrator vibrates to make it smooth;

[0028] (4) Demoulding: 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 demoulding time is 3-4 hours; above 2...

Abstract

The invention provides a ceramsite concrete light-weight partition board and a preparation method thereof. The partition board is characterized by comprising the following components in weight ratio: 58-75% of ceramsite, 13-21% of cement, 10-21% of slag and 0.5-1.7% of water reducing agent. The partition board solves the problem that such partition boards widely used in the buildings at present as strengthened plant fiber boards, aerated cement boards, slag and flyash boards, flyash, gravel and cement boards, gypsum boards and the like have high water absorption, short lives, low overall structural strength and low anti-impact and anti-bending loads, are liable to aging, cracking and deforming with heat and cold, can not be nailed, drilled and transversely and longitudinally threaded and the like, and is suitable for serving as a non-bearing partition board in the buildings.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a lightweight concrete partition wall board with ceramsite as aggregate and slag as auxiliary material. 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 w...
