This fact shows an inverse relationship between the amount of rubber added and the density of the mortar. Regarding the size of the incorporated rubber, in the case of cement C1 mortars, the densities are higher when the rubber used is larger (T1). In the case of cement C2 mortars, medium size rubber mortars (T2) have slightly higher densities.

An end-of-Life Tyre (ELT) is a type of waste that can generate negative social and environmental impacts due to its disposal. Considering that rubber can improve concrete properties and the massive use of concrete as construction material, the addition of ELT rubber in concrete mixes is attractive. However, concrete mechanical properties are negatively affected due to the rubber-cementitious ...

Cement Phase - an overview ScienceDirect Topics

The cement phase can be preblended or mixer blended, although the former is limited to a maximum of 55% of cementitious content in EN 206 and thus just within the HVFA range. Given the low free water contents and water/cement ratio used with HVFA, super plasticizing chemical admixtures are used to achieve the required workability.
