Tech Paper On Use Of Baryte In Cement

MODEL QUESTION PAPER 1 Concrete Technology

water cement ratio also increases hence the strength of concrete decreases. Cement Content: Use of more cement increases workability, but leads to uneconomical mix and shrinkage. Aggregate-Cement Ratio: For high aggregate-cement ratio (i.e. for the lean mix) less paste will be available for lubrication hence, the workability reduces.
