dry-mix – the dry mixture of cement and aggregates is filled into the machine and conveyed with compressed air through the hoses. The water needed for the hydration is added at the nozzle. wet-mix – the mixes are prepared with all necessary water for hydration. The mixes are pumped through the hoses.
The output obtained from a site mix concrete plant using a 8/12 mixer is 4 to 5 metric cubes per hour which is 30-60 metric cubes per hour in a ready mix concrete plant. Better handling and proper mixing practice will help reduce the consumption of cement by 10 – 12%.
[2] The bar has a mass of approximately 54.5g [3] although multipack bars are smaller at 37.3g. [4] This increased from 42g in the 1970s and 51g in the 1980s, to a peak of 60g before attaining the current weight. It typically contains 9.9g of fat, 38g of carbohydrates, 2.3g of protein and 1060kJ (250kcal) of energy.
The global Ready Mix Concrete (RMC) market is valued at US$394.44 billion in 2017 and is expected to reach US$624.82 billion by the end of 2025, growing at a CAGR of 5.92% between 2016 and 2022. [2] A ready mix concrete plant is generally located inside the city, transporting ready-mixed concrete for projects through concrete truck mixers.
Foamed concrete can be produced with dry densities of 400 to 1600 kg/m 3 (25 lb/ft 3 to 100 lb/ft 3), with 7-day strengths of approximately 1 to 10 N/mm 2 (145 to 1450 psi) respectively. Foam concrete is fire resistant, and its thermal and acoustical insulation properties make it ideal for a wide range of purposes, from insulating floors and ...

A w/c ratio higher than 0.60 is not acceptable as fresh concrete becomes "soup" [2] and leads to a higher porosity and to very poor quality hardened concrete as publicly stated by Prof. Gustave Magnel (1889-1955, Ghent University, Belgium) during an official address to American building contractors at the occasion of one of his visits in the ...
