SciELO - Brasil - Thermal properties of polypropylene and

Concrete is one of the materials most used by the construction industry. Reinforcing this material with fibers is a technique used to improve its mechanical properties. Steel and polymer fibers are the main types used in this application and there are few studies about the influence of polymer fibers on the thermal properties of concrete.

Development of properties as a function of curing

This involves an examination of the influence of the curing temperature on the development of properties such as compressive strength and resistance against chloride ingress. Preliminary results indicate that the original maturity function probably needs to be revised in order to be consistent with the types of concretes used nowadays.

Investigations of the Influence of Polystyrene Foamed

This paper deals with the behaviour of cement paste upon the addition of crushed polystyrene foam. Crushed polystyrene foam waste with a fill density of 13.97 kg/m3 and hydrated lime were used to prepare the foam. Three different types of samples S-1, S-2, and S-3 were prepared to observe the behaviour of cement pastes after the addition of different doses of foam in constant water/cement

Effect of Curing and Composition on the Properties of the

The skin quality was determined by absorption tests and depth of carbonation (natural and accelerated). It has been found that a deficient water treatment in a hot and dry environment could have a mild negative effect on strength, but a marked detrimental influence on the properties of the skin, particularly in high‐fly‐ash content concretes.
