Study on the Preparation of Non-fired Bricks by Solidified dredged soil

摘要

A non-fired brick were manufactured by solidification of modified dredged soils. A novel solidified agent based on industrial wastes was prepared. A typical manufacture process of the non-fired brick comprised of mixing, stirring, tamping and maintaining. Several tests and measurements were conducted according to Chinese Professional Standard and National Standard. The results showed that the non-fired brick exhibited excellent performances and low toxicity. The non-fired brick was found to be a suitable material for use in the civil architecture.
