Benefits of technology

This patented technology uses waste cerams or building demolition residues (WSR) for making stronger brick that can be used repeatedly without being thrown away after use. It does this by reducing both environmentally harmful emissions from disposal and producing more efficient energy sources than current options like coal burning power plants due to its ability to absorb moisture even when it becomes wet during rainwater cycles. Additionally, with these new technologies, there will no longer require expensive equipment such as kilns at home instead relying on conventional concrete blocks made up mostly sandstone material. Overall, this innovation helps reduce greenhouse gas emission while improving sustainably available renewables supplies through reuse.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the properties or quality of porous brick that can effectively remove excess moisture without causing environmental damage during its fabricating processes.

Abstract

The invention discloses a baking-free water-permeable brick, which comprises the following raw material compositions by weight: 60 to 75 percent of aggregate and 25 to 40 percent of adhesive; the aggregate is scrap of building ceramics, sanitary ceramics and building materials; and the adhesive is quick-setting inorganic adhesive. The invention also discloses a method for manufacturing the baking-free water-permeable brick. The baking-free water-permeable brick utilizes mass waste ceramics and other building scrap as the raw materials, is formed by adopting the quick-setting inorganic adhesive to adhere and solidify, does not need a high-temperature sintering procedure, has short solidifying time and reduces the pollution to the environment and the production cost at the same time. The method effectively recycles the waste resource, greatly reduces the environmental pressure and realizes the recycling of the resource; and the manufactured water-permeable brick has high water permeability and good compression-resistant and wearproof strength.
