Embodiment 1

[0020] A method for making lightweight high-strength water-permeable sidewalk bricks, characterized in that the method includes the following steps:

[0021] Mixture preparation: convert the sludge cake, slag and river and lake dried bottom sludge into 0% water content and then prepare according to weight parts. When preparing, add 100kg of sludge cake to every 200kg of slag , adding 500kg of dried river and lake bottom mud, wherein the slag particle size is less than or equal to 2mm, mixed and aged for 1 week, and the moisture content of the mixed material is determined to be equal to 8%, which is used to make road brick blanks;

[0022] Road brick molding: fix the ribs on the bottom plate of the mold, add the mixture into the mold cavity, and use the shock pressure road brick press to press the mixture. The shock force of the shock pressure road brick press is controlled at 40KN , the vibration frequency is controlled at 4000 times / min, and the amplitude is controlled at 10m...

Embodiment 2

[0030] A method for making lightweight high-strength water-permeable sidewalk bricks, characterized in that the method includes the following steps:

[0031] Mixture preparation: convert the sludge cake, slag and river and lake dried bottom sludge into 0% water content and then prepare according to weight parts. When preparing, add 300kg of sludge cake to every 200kg of slag , adding 700kg of dried river and lake bottom mud, wherein the slag particle size is less than or equal to 2mm, mixed and aged for 2 weeks, and the water content of the mixed material was determined to reach 16%, which was used to make road brick blanks;

[0032] Road brick molding: fix the ribs on the bottom plate of the mold, add the mixture into the mold cavity, and use the shock pressure road brick press to press the mixture. The shock force of the shock pressure road brick press is controlled at 68KN , the vibration frequency is controlled at 5000 times / min, and the amplitude is controlled at 15mm;

Embodiment 3

[0040] A method for making lightweight high-strength water-permeable sidewalk bricks, characterized in that the method includes the following steps:

[0041] Mixture preparation: convert the sludge cake, slag and river and lake dried bottom sludge into 0% water content and then prepare according to weight parts. When preparing, add 200kg of sludge cake to every 200kg of slag , add 600kg of river and lake dried bottom mud, wherein the slag particle size is less than or equal to 2mm, mix and age for 10 days, measure the moisture content of the mixture to 12%, and use it to make road brick blanks;

[0042] Road brick molding: fix the ribs on the bottom plate of the mold, add the mixture into the mold cavity, and use the shock pressure road brick press to press the mixture. The shock force of the shock pressure road brick press is controlled at 50KN , the vibration frequency is controlled at 4300 times / min, and the amplitude is controlled at 13mm;

Abstract

The invention relates to a method for making sidewalk bricks with light weight, high strength and high water permeability. The production method comprises the following steps: preparation of mixture, molding of road bricks, drying, stacking kiln and roasting. The method has sufficient raw materials and can effectively Purify the environment, reduce pollution sources, quickly absorb the accumulated water on the brick surface, save external roasting energy consumption, and be more firmly combined with the cushion mortar during construction, not easy to loosen, and the weight of the fired bricks is lighter.

Description

technical field [0001] The invention relates to a brick-making method, in particular to a method for making sidewalk bricks with light weight, high strength and high water permeability by using river and lake bottom mud and domestic sludge as raw materials, improving the shape of traditional products, and sintering. Background technique [0002] Traditional sidewalk bricks (commonly known as bread bricks) are made of cement, stone chips, and fly ash as raw materials. They are bulky, have poor water absorption, and are not firmly combined with the cushion mortar (easy to loosen); Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, provide a kind of raw material sufficient, purify the environment, reduce the pollution source, can quickly absorb the accumulated water on the brick surface, save external roasting energy consumption, and be compatible with the cushion layer during construction. A method for ma...
