Abstract

This invention relates to a formula for producing concrete bricks with foundry antiquated sand characterizing that the raw material of the wet blank of said brick is composed of the following components in terms of the weight percentage: foundary antiquated sand 10-45, powdered coal ash 15-30, slag 8-26, cement 15-21, water 6.5-12, water repellent 0-0.6, water glass 0-2.2, river sand 0-30, and the technical flow includes: preparing enough foundary antiquated sand with the grain diameter below 4mm, powdered coal ash, slag, river sand, enough cement, water water repellent and water glass, weighing them in terms of the above mentioned proportion and mixing them uniformly to make up of a mixed material to be put in a prepared model to be pressed with a press to shape the mixed material, then taking out the mixed material from the model to get a concrete wet blank to be air-dried to get the product.

Description

[0001] 1. Technical field: The present invention relates to a raw material formula and a production method for producing building wall component materials using foundry waste sand. 2. Background technology: [0002] The annual discharge of foundry waste sand in my country is more than 10 million tons. Due to improper treatment technology, it not only pollutes the environment, but also causes a lot of waste of resources. Taking Beijing as an example, 11.56 million tons of industrial solid waste is generated every year, and the comprehensive utilization amount is 9.49 million tons. 550,000 tons have been properly treated (with low treatment technology), and 1.52 million tons have been piled up in the environment. The stock has reached 114.75 million tons, covering an area of ​​3.75 million square meters. In 1995, the state promulgated the Law of the People's Republic of China on the Prevention and Control of Environmental Pollution by Solid Waste (revised for the first time in ...
