Concrete Manual: A Manual for the Control of Concrete Construction

Information is presented on prestressed concrete. Benefication of aggregate by heavy-media separation, elastic fractionation and hydraulic jugging and benefication of sand through attrition are discussed. Currently a reexamination of the effect of maximum size aggregates is being made, and significant results to date are included. The use of water-reducing, set-retarding admixtures is sometimes advantageous. Their application and use, together with precautions to be considered, are described. Thermosetting plastics, principally epoxy resins, have great versatility. Their application to bonding of concrete and their use in minor repairs are presented.

Information is presented on the application of mortar lining and coating to steel pipe. Methods of test for pozzolan acceptance, evaluation tests for chemical admixtures, a test for lightweight particles in aggregate, and a relative humidity test for concrete masonry units are included for the first time as test designations. The section on concrete pipe manufacture and testing has been enlarged to reflect changes in specifications. A checklist of inspection items for field construction, which should be helpful to inspectors, is included.
