Abstract

The invention discloses a novel baking-free brick. The novel baking-free brick is prepared from the following raw materials in parts by weight: 10 to 20 parts of coal ash, 25 to 35 parts of building waste, 20 to 40 parts of cement, 8 to 17 part of oil field sludge, 5 to 15 parts of river sand, 7 to 13 parts of blast furnace slag, 15 to 22 parts of aggregate, 6 to 13 parts of quick lime, 3 to 7 parts of phosphogypsum, 1 to 3 parts of activating agent and a proper amount of water. The novel baking-free brick is wide in source, is low-cost, has high compression strength, and is corrosion-resistant; the use ratio of the river sand is lowered, waste is utilized fully, energy is saved, and environment is protected.

Description

Technical field [0001] The invention belongs to the field of building materials, and specifically relates to a novel non-fired brick and a preparation method thereof. Background technique [0002] Non-fired bricks, also known as non-fired bricks, have been widely used in the construction field because they can avoid the serious waste of land resources and the environmental pollution caused by SO2 emissions during the preparation process. In the prior art, non-fired bricks Use river sand or river sand as the main raw material, and then add a certain amount of auxiliary raw materials such as cement, fly ash, aggregate, etc. After hardening, the cement can be used as a binding material, fly ash as a filler material, and aggregate as a reinforcing material. River sand or river sand is a material with limited resources, and the price is relatively high. Therefore, non-burning bricks made of river sand or river sand are expensive and not conducive to energy saving. Summary of the inve...
