TH33770A - A new type of binder in concrete - Google Patents

Abstract

DC60 (26/10/41) Coal ash mixed with calcium carbide residue can be used as a binder. It is a new type of cement. The process for producing binder has to make the particle size of Both materials are small and then mixed together. By using the mixture of coal ash to sludge Calcium carbide equal to 7030 by weight to be used as a binder in concrete of columns, beams or building floors in general, mortar, plastering, as well as making concrete blocks, both supporting and Not able to withstand heavy loads or concrete bricks. Coal ash mixed with calcium carbide residue can be used as a binder. It is a new type of cement. The binder production process has to make the particle size of The two materials are small and then mixed together. By using the mixture of coal ash to sludge Calcium carbide equal to 70:30 by weight for use as a material in concrete work of columns, beams or building floors in general, mortar, masonry, plastering, as well as making concrete blocks, both supporting and Can not withstand heavy loads or concrete bricks:

Claims (6)

1. New binder consisting of a mixture of coal ash and calcium carbide residue. 2. The new binder production process has the following production steps. A. Ground calcium carbide residue with a grinder to a small particle size. B. Remove the crushed calcium carbide residue with a particle size separator. Particles smaller than 75 μm. C. Separate the prepared coal ash with a particle size separator to a particle size smaller than 75 μm. Coal ash against calcium carbide residue was 70:30 by weight. 3. Process according to claim 2: Calcium carbide waste that is dried in the sun or burned to a temperature of 800 ํ C 4. Process according to claim 2, when a higher compressive strength is needed, it can be done by using a mixture of chemicals such as water reducing agent, special water reducing agent. Formation retardants or accelerators in the mixture To reduce the ratio of water to binder to be lower 5. Process according to claim 2 When a higher compressive strength and a faster time of formation at an early age can be achieved by adding cement or lime to the mixture. 6. The new binder according to claim 1 is the use of a binder in mortar or concrete by mixing the binder with water and mixing together until a paste is used. In the work of reinforced and non-bearable concrete blocks, concrete bricks, masonry, plaster, columns, beams or concrete building floors in general. Also used in the development of soil and cement columns (Cement Column)
