In large work or in major construction works, cement is generally stored at site. The cement must be stored in such a manner so that, it can be easily accessible for proper inspection. The building in which cement is stored should be water tight in order to prevent dampness. The guidelines given below should be observed while storing the cement. 1. Cement should not be stored for a long period. During rainy season, the storage time period of cement should be as minimal as possible. 2. Dampness in godowns must be avoided. 3. Cement should not be piled against the wall. A minimum space of 60 cm all –round should be left between the exterior walls and the stacks. The distance between two consecutive stacks should be minimum to reduce circulation of air. 4. Cement should not be piled directly on the floor; instead it should be piled off the floor on wooden planks/crates so as to be clear off the floor by at least 10 to 20 cm. 5. There should not be more than 15 bags in one pile. This...

ADVANTAGES OF PRECAST CONCRETE Following are the advantages of precast concrete: 1. The concrete of superior quality is produced as it is possible to have better technical control on the production of concrete in factory. 2. It is not necessary to provide joints in the precast construction. 3. The labour required in the manufacturing process of the precast units can easily be trained. 4. The moulds employed for preparing the precast units are of steel with exact dimension in all directions. These moulds are more durable and they can be used several times. 5. The precast articles may be given the desired shape and finish with accuracy. 6.The precast structures can be dismantled, when required and they can then be suitably used elsewhere. 7. The transport and storage of various components of concrete for cast in-situ work are eliminated when precast members are adopted. 8. The work can be completed in a short time, when precast units are adopted. 9. When precast structures are to be ins...
