rmc concrete tests

What is ready-mix concrete or RMC and what are the types?

Tests should be conducted to establish the requirement of mixing the drum mixer. 3. Central mixed concrete. Central-mixing concrete Batch plants include a stationary, plant-mounted mixer that mixes the concrete before it is discharged into a truck mixer. Central-mix plants are sometimes referred to as wet batch or premix plants.
