The middlemen or cement brokers influence the Indian cement market in a significant manner as they directly buy bulk cement from the manufacturers, suppliers and sell it to the cement buyers like construction business, cement importers, retailers, etc. The involvement of the middlemen leads to a sizeable in-line credit price, which is the fundamental reason behind the high MRP of cement for the buyers. read more
Aggregate is a collective term for the mineral materials such as sand, gravel and crushed stone thatare used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form
compound materials (such as asphalt concrete and portland cement concrete). Aggregate is also usedfor base and subbase courses for both flexible and rigid pavements.
Aggregates can either be natural or manufactured. Natural aggregates are generally extracted from larger rock formations through an open excavation (quarry). Extracted rock is typically reduced tousable sizes by mechanical crushing. Manufactured aggregate is often the byproduct of other manufacturing industries. read more
1. Transit mixed concrete
It is also called dry batched concrete because all the basic ingredients including water are charged directly into the truck
mixer. The mixer drum is revolved fast at charging speed during the loading of the material and after that it continues rotating at a normal agitating speed. In this type of ready mix concrete, also three types of variations are possible as given below: read more
Ready mix concrete that is concrete that is manufactured in a factory or batching plant, according to a set recipe, and then delivered to a work site by truck mounted in–
transit mixers. This results in a precise mixture, allowing specialty concrete mixtures to be developed and implemented on construction sites. The first ready-mix factory was built in the 1930s, but the industry did not begin to expand significantly until the 1960s, and it has continued to grow since then. It is often preferred over on-site concrete mixing because of the precision of the mixture and reduced work site confusion. Ready-mix concrete, or RMC as it is popularly called, refers to concrete that is specifically manufactured for delivery to the customer’s construction site in a freshly mixed and plastic or unhardened state. read more

There is no compelling reason to aimlessly take after the pattern. Knowing their properties, prescribed utilizations, money saving advantages, and so forth will give you a superior thought regarding which concrete ought to be utilized and where it ought to be utilized. read more
Soundness of concrete is the property of solidified bond glue experiencing extensive change involume in the wake of setting without postponed ruinous development. This dangerous development iscaused by intemperate measures of free lime or magnesia. This adjustment in volume may cause crackand breaking down of cement. Soundness of bond can be checked by utilizing Le-Chatliers apparatus.Soundness is only volumetric difference in the concrete .Presents of chemicals, for example, CaO,MgO will respond with the water show in the bond glue and it will expand the volume ofcement glue while solidifying. It might makes breaks in the building maintain a strategic distance from that it is necessaryto discover the soundness of concrete before utilizing that. It might fluctuate to each kind of bond even foreach clump. Soundness ought not surpass 10mm for OPC read more
The most widely recognized use for Portland cement is in the generation of cement. Concrete is a composite material comprising of total (rock and sand), cement, and water. As a development material, cement can be thrown fit as a fiddle wanted, and once solidified, can turn into a basic (stack bearing) component. Cement can be utilized as a part of the development of auxiliary components like boards, shafts, and road furniture, or might be thrown in situ for superstructures like streets and dams. These might be provided with concrete blended nearby, or might be furnished with ‘prepared blended’ cement made at perpetual blending locales. Portland cement is likewise utilized as a part of mortars (with sand and water just), for mortars and screeds, and in grouts (cement/water blends crushed into holes to unite establishments, street beds, and so forth.). read more
