The mix ratio for M25 concrete is typically expressed in terms of the proportions of cement, water, fine aggregate (such as sand), and coarse aggregate (such as gravel or crushed stone) used in the mix. A common mix ratio for M25 concrete is 1:1:2, which refers to a mix that contai...

Concrete mixes in 1:2:4 ratios of cement, sand and SSA; batched by weight, and a water cement ratio of 0.6 were considered. However, a control mix using normal aggregate (NA) was made in order to evaluate the variation in properties of the concretes. The study utilised SSA and NA ...
According to the construction site sand and stone watercontent adjustment after adjustment is called construction mix ratio. It is assumed that themixing ratio of the laboratory is cement: sand: stone = 1: x: y, water ashratio is W/C, the water content of the construction site is Wsa, th...
The concrete mix ratio PKS:PKF of 50:50 for 1:1:3 and 1:2:4 has compressive strength of 12.29N/mm 2 and 10.38N/mm 2 after 28 days, which confirms light weight concrete. Thus, from the result obtained from this research, both palm kernel shell and palm kernel fiber could be used ...
The concrete mix adopted was 1:2:4 (cement: sand: granite/recycled aggregate) with w/c ratio of 0.55 by weight. The percentage replacement of normal coarse aggregate by recycled aggregate was 0% for forty (40) beams and 30% for the remaining forty (40) beams. Six (6) cubes for each...
Three concrete samples were fabricated using a concrete mixture having a cement-to-sand-to-aggregate ratio of 1:2:2, by weight. The first sample contained a smooth, unbroken surface; half of the sample was coated with paint, to prevent the observation of fluorescence, while the other half ...
This paper presents some of the practical results of this approach in terms of design limits and mix design recommendations. Design guidance is given such that a matrix of factors may be optimised, including water/binder ratio, binder type, cover depth, environment, and construction practice, in...

Nominal mix ratios of 1: :3, 1:2:4 and 1:3:6 were prepared using two different water/cement ratios, that is 0.5 and 0.6. Five different sizes of coarse aggregates, that is, 5mm, 12mm, 20mm, 25mm, and 38mm were used. The concrete cubes cast were cured for the period of 14 and...
