Factors Affecting Quality Control Of Concrete

what is durability of concrete? factors affecting,factors affecting the durability of concrete. so the volume of chloride content must be controlled in construction materials. ensure the quality of material used in concrete and do some field tests to check the material quality. use the right type of cement for construction work..quality control of crops and factors affecting quality of,the quality of crop produced is as important as the quantity produced, or more important than that. for example, it is desirable to produce fine rice with pleasant aroma, wheat with high milling quality, maize with a high percentage of marketable grain to stalk, cotton with long fibres, groundnut with low percentage of hull, sugarcane with high sucrose, potatoes with good cooking quality etc..
