What are advantages and disadvantages of ready mix concrete?

Answer 1

ADVANTAGES OF RMC:

· Speedy construction through continuous mechanized operations leading to economy.

· Lower labor and supervisory costs assured.

· Multi- transportation of raw materials for concrete is eliminated.

· Controlled W/C ratio.

· Close quality control of batching reduces variability of the desired properties of hardened concrete.

· Use in congested sites or in highway construction where there is little space for a mixing plant and aggregate stocking.

· Use of agitator trucks to ensure care in transportation, thus preventing segregation and maintaining workability.

· Minimization of cement wastage in view of bulk handling of storage.

· It can be supplied with required slump and consistency

· Useful additives like fly ash, plasticizers, retarders can be added to enhance the properties under controlled condition.

DISADVANTAGES OF RMC:

Since RMC is a bought commodity it is costlier by about 10 to 15% than concrete mixed at site.
