Mix Design For C30 Grade Concrete
· concrete structure design. For the use of FMT concrete in the structures, the FMT concrete elastic modulus must be determined. In this program, 21 specimens of 150mm×150mm×300mm are fabried and tested, with 3 specimens in each strength grade of C30, C35, C40, C45, C50 and C55. The concrete mix proportions are the same as Table 7. The test ...

Reactive transport modelling of concurrent chloride ...
· The solubility of C–S–H can be modelled using solid solution models [35, 36] or through a continuous approach using the C/S ratio, x, as a continuous variable [].Both models are equivalent but the latter approach has been proved to be effective for numerical simulations [32, 37, 38].This approach leads to a phase diagram [31, Fig. 1] and an equilibrium solubility product both depending on ...

Manufacturing Light Concrete with PET Aggregate
· The manufacture of concrete using a polymer instead of a stony coarse aggregate known as gravel is presented. Polyethylene terephthalate (PET) is the polymer used, recycling soft drink containers with sufficient tenacity . PET is a material commonly used by engineers as a structural element, not as an aggregate. The research work revealed that PET aggregate produces good quality .
