It is suggested that 50% copper slag should be used instead of sand and 18% fly ash should be used instead of cement to obtain high strength concrete.
The mineral additives used in cement production, such as limestone, fly ash, slag and pozzolan, are increasing year by year. On the other hand, it is well known that if the clinker content is reduced, the performance of cement can be improved.
Slag cement is composed of ordinary portland cement, ordinary portland cement, ordinary portland cement and ground blast furnace slag. It has been used for many years in the construction industry all over the world.
The strength of grade 53 cement is as high as 70 MPa, while the minimum strength specified by BIS is 53 MPa. Therefore, we can also mix at least 20 weight of fly ash in concrete as a partial substitute of cement on site. This not only saves the material cost of concrete, but also achieves the durability of concrete with smaller porosity due to the refinement of pores.

The use of fly ash as a cement component has been very mature, and its application has enhanced 187 more detailed contents.
The same substitution rate is used in type II concrete, but only 100 RA is found in type III concrete. There are four concrete mixtures made of high content FA cement with 40, 50, 60 and 70 alternatives to OPC. This paper provides information on mix design, fully demonstrating the CO 2 footprint and the cost, hardening and.

On March 30, 2015018332raffia said that pozzolan and slag are considered to be materials that can provide buildings with a service life of more than 40 years. According to our estimation, Dubai will save 192 million dirhams due to the extended service life.
UAE Renca technology start-up, in collaboration with the Dubais Future Accelerators program, has developed a geopolymer cement made from fly ash and ground slag for 3D printing. Compared with ordinary portland cement, the advantage of the product used in additive manufacturing is that it can be cheaper without additives.
The substitution rate of ordinary portland cement is increasing rapidly, which promotes the demand for green cement. Green cement market has been subdivided according to end users and geographical location. Different types of green cement include fly ash cement, slag cement, recycled aggregate cement and others.

March 30, 2015 2015018332 by using these alternatives, the carbon footprint of concrete can be reduced by 45%, he said. The UAE construction industry relies on more than a dozen foreign cement manufacturers currently producing about half the tonnage, which will now increase the production of fly ash and GGBS.
Auxiliary cementitious material is a kind of material that can be used to make concrete, as a partial substitute of Portland cement. The most commonly used SCM are fly ash (a byproduct of coal-fired power plants), ground blast furnace slag (slag from steel production) and silica fume (also known as micropowder).
The pozzolanic materials used as additives include natural pozzolan and artificial pozzolanic ash, clay shale, volcanic tuff, pumice, etc., and the available artificial pozzolans include fly ash, silica fume, blast furnace slag, rice husk ash, soda ash, etc.
