Non-destructive Testing Of Concrete By Rebound Hammer By Kaushal Kishore Materials Engineer‚ Roorkee INTRODUCTION The standard method of determining strength of hardened concrete consists of testing concrete cubes in compression. The quality of entire concrete of a structure cannot be fully assessed by testing a few concrete cubes. The results obtained in testing cubes do not always reflect the actual strength of concrete in construction. In a whole day‚ concreting work cubes are cast in

Title : Concrete Cube Compressive Strength (7 days) Introduction : To determine the strength‚ maximum load can be applied and workability of concrete mixture. Theory : Hard concrete test were conducted at the age of 3‚ 7‚ 14‚ 21 and 28 days after curing(but we tested it for 7 days only). The concrete strength increases according to the age‚the mixture of its concrete design and the strength increment will continue for sometimes. Nevertheless‚ for most of the work‚ the concrete strength on

Some of them of the great things that they have built include; concrete‚ roads and arches. With these inventions and several more‚ the Romans have changed the art of buildings for ever. Without it the world would not be the same‚ and it would affect our world forever. One of the first inventions that the Romans made‚ was concrete. Concrete was used to be made as a glue like substance for building structures. The Roman concrete was made of lime‚ seawater and volcanic ash. According to the Article

Concrete mixer which is also commonly named as cement mixer is a device that homogeneously combines cement‚ aggregate such as sand or gravel‚ and water to form concrete. History Why did man invent concrete mixer? The reason of it is that in the early 20th century‚ the concrete was developed when some new materials added to cement. After the concrete was developed‚ the art of mixing it had to reform. Therefore‚ concrete mixers were becoming pretty popular by early 20th Century. This coincided
