The present invention relates to a novel composition which is useful for forming construction blocks and encapsulating hazardous materials, a process for producing blocks and encapsulating the material, and blocks made of the material. This composition is a mixture of kiln dust or volcanic fly ash and aggregate. The process comprises the steps of (a) blending a dry mixture comprising the kiln dust or volcanic fly ash mixture with water; (b) transferring the blended mixture into a compression zone and (c) compressing the blended mixture in the compression zone to form a brick of the desired size.
