Ready mix concrete is a modern trend of introduction in the Asian Countries. It is already introduced long before in the European Countries. It is new concept of use concrete in the construction area. Ready mix concrete has advantages in the area where immediate requirement of concrete mixture like in the preparation of bridge overhead roads on or the road construction. In India there is a hopeful to get good scope of RMC within short period. The batching, mixing, transportation, placing, compaction, finishing and curing are very complimentary operations to obtain desired good quality concrete. The good quality concrete is a homogeneous mixture of water, cement, aggregates and other admixtures. Admixtures are chemical mixtures that are added to concrete to enhance its performance is some fashion. Admixtures are materials other than cement, aggregate and water that are added to concrete either before or during its mixing to alter its properties, such as workability, curing temperature range, set time or color. Some admixtures have been in use for a very long time, such as calcium chloride to provide a cold-weather setting concrete. Others are more recent and represent an area of expanding possibilities for increased performance. Not all admixtures are economical to employ on a particular project. Also, some characteristics of concrete, such as low absorption, can be achieved simply by consistently adhering to high quality concreting practices. The aim of quality control is to ensure the production of concrete of uniform strength in such a way that there is a continuous supply of concrete delivered to the place of deposition, each batch of which is as nearly like the other batches as possible. India is the second largest producer of cement in the world after China. Cement and ready-mix concrete demand is dependent on the level of construction activities. Construction activities are in turn closely related to a number of macroeconomic factors such as consumer spending, population growth, manufacturing sector growth, inflation rates, government spending etc. The construction industry is the second largest industry in India after agriculture. It accounts for about 11% of India’s GDP. It makes significant contribution to the national economy and provides employment to large number of people. Construction constitutes 40% to 50% of India's capital expenditure on projects in various sectors such as highways, roads, railways, energy, airports, irrigation etc. There are mainly three segments in the construction industry like real estate construction which includes residential and commercial construction; infrastructure building which includes roads, railways, power etc; and industrial construction that consists of oil and gas refineries, pipelines, textiles etc. Building material is any material which is used for a construction purpose. Many naturally occurring substances, such as clay, sand, wood and rocks, even twigs and leaves have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use. According to a study by ASSOCHAM, the burgeoning Indian construction industry, currently worth $70 billion, will rise to US$120 billion by 2010. The Ready-mix concrete business in India is in its nascent stage. In a developed country 70% of cement produced is used by the Ready-mix concrete industry. However, in India, the Ready-mix concrete industry uses less than 10% of the total cement production. A large and growing middle class population of more than 300 million people, a changing life style, better cost of living etc is growth drivers for this sector. There is good scope to venture into this field for new entrepreneurs. Few Indian Major Players are as under: A C C Concrete Ltd. Ahlcon Ready Mix Concrete Pvt. Ltd. Ahluwalia Contracts (India) Ltd.
