Fly Ash Types. Currently, more than 50 percent of the concrete placed in the contains fly ash. Dosage rates vary depending on the type of fly ash and its reactivity level. Typically, Class F fly ash is used at dosages of 15 to 25 percent by mass of cementitious material, and Class C .

Fine aggregate of grading as given in Table 2 is best for pumped concrete. The proportion of fine aggregate (sand) to be taken in the mix design is given in Table 3. However, the lowest practical sand content should be established by actual trial mixes and performance runs. ... Comparative Study of concrete mix design using IS and ACI methods ...

The volume of mix is sufficient to produce 3 numbers of cube and to carry out the concrete slump test. The volume of mix is multiplied with the constituent contents obtained from the concrete mix design process to get the batch weights for the trial mix. The mixing of concrete is according to the procedures given in laboratory guidelines.

Concrete Mix Ratios Cement, Sand, Aggregate and Water

Concrete Mix Ratios Cement, Sand, Aggregate and Water

Concrete mix ratio is a vital topic in concrete mix design. The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.

respectively. The development of mix design is based on many factors such as alkaline liquid to fly ash ratio, Na 2 SiO 3 to NaOH ratio, molarity of NaOH, type of curing methods, temperature and rest period etc. The concrete mix is designed by using all the above parameters and specimens were casted then tested on 3rd, 7th
