Embodiment 1

[0052] The production volume density is 1300 kg / M 3 High-volume fly ash load-bearing ordinary solid brick, take fly ash containing SiO 2 48.5%, quicklime contains 70% CaO, and the sand is coarse and medium sand.

[0053] Its implementation steps are as follows:

[0054] Step 1: Take C / S=0.50 to design the mixture ratio.

[0055] Assume: the percentage of fly ash content is X, the percentage of quicklime content is Y, and they are substituted into the following formula for calculation:

[0056] X + Y = 70 % C 1 × Y / ( S 1 × X ) ...

Embodiment 2

[0067] The production volume density is 1000 kg / M 3 , non-load-bearing high-volume fly ash modulus hollow brick with a porosity of 31%, the fly ash containing SiO 2 48.5%, quicklime contains 70% CaO, with slag as aggregate.

[0068] Its implementation steps are as follows:

[0069] Step 1: Take C / S=O.30, and carry out the mixture ratio design.

Abstract

The invention is a highly doped powder coal ash brick and its making method, and its technical project: it contains powder coal ashes, stove ashes, calcium oxide, and aggregate and its characteristic: the ratio of the effective component CaO in calcium oxide to effective component SiO2 in powder coal ashes or stove ashes C / S = 0.30-0.50. The invention discloses a corresponding making method, including the necessary steps of routine form process of powder coal ash brick and also including the steps of regulating C / S at 0.30-0.50, ageing and acvitating mixed material, and then pressing strick blanks and making high-tempeatrue and high-pressure curing. Its products have out-kettle strength higher than that of eixisting powder coal ash bricks, dried shrinkage reduced by 40-50%, good carbonization resistance and stable durability for long time, and it can cooperate with existing building modulus, it is beneficial to environmental protection and using waste, and easy to spread and implement.

Description

technical field [0001] The invention relates to a fly ash brick and a manufacturing method thereof, in particular to a high-volume fly ash brick and a manufacturing method thereof, belonging to the field of new environment-friendly building materials. Background technique [0002] At present, in the field of building materials, there are three types of non-sintered fly ash brick production technologies: non-steamed fly ash bricks, steam-cured fly ash bricks and autoclaved fly ash bricks. Non-steaming fly ash bricks are naturally cured at room temperature, and steam-cured fly ash bricks are cured by ordinary steam at 90°C to 100°C. Due to the low curing temperature, no matter what the ratio of raw materials is, it is impossible to form relatively high There are many crystallized and complete hydration products, so the product strength is low, the shrinkage value is large, shrinkage cracks are easy to occur, the weather resistance is weak, the durability is poor, and the produ...
