Cement is a mineral hydraulic binder which is formed by sintering (heat treatment) primary minerals of cement clinker at a sintering temperature. In the cement composite only cement releases heat by reaction with water, and image about the amount of heat or about temperature of solid concrete is obtained by determination of the heat of hydration of...

In recent decades the production of chemically bonded refractory materials has been clearely increased. In this paper was examined the added amount effection of 50% solution of mono aluminum phosphate (MAP) as a binder in refractory concretes. Quartz, sand and chamotte are used as fillers. Research has shown that the bond between the filler and the...

For the production of self-compacting concrete for a specific application, with desired properties in fresh and hardened state, it is necessary to combine the constituent materials in the optimum proportions. The proportioning of self-compacting concrete has to start with defining the required properties. For a particular application, a self-compac...
