Abstract EN
The mechanical properties of concrete containing self-curing agents are investigated in this paper.
In this study, two materials were selected as self-curing agents with different amounts, and the addition of silica fume was studied.
The self-curing agents were, pre-soaked lightweight aggregate (Leca) ; 0.0%, 10 %, 15%, and 20% of volume of sand ; or polyethylene-glycol (Ch.); 1 %, 2 %, and 3% by weight of cement.
To carry out this study the cement content of 300, 400, 500 kg/m3, water/cement ratio of 0.5, 0.4, 0.3 and 0.0 %, 15 % silica fume of weight of cement as an additive were used in concrete mixes.
The mechanical properties were evaluated while the concrete specimens were subjected to air curing regime (in the laboratory environment with 25 C, 65% R.H.) during the experiment.
The results show that, the use of self-curing agents in concrete effectively improved the mechanical properties.
The concrete used polyethylene-glycol as self-curing agent, attained higher values of mechanical properties than concrete with saturated Leca.
In all cases, either 2 % Ch.
or 15 % Leca was the optimum ratio compared with the other ratios.
Higher cement content and/or lower water/cement ratio lead(s) to more efficient performance of self-curing agents in concrete.
Incorporation of silica fume into self-curing concrete mixture enhanced all mechanical properties, not only due to its pozzolanic reaction, but also due to its ability to retain water inside concrete.
