the sustainability of the built environment is increasingly coming to the forefront of infrastructure design and maintenance decisions. to address this, development of a new class of more sustainable cement-based materials is needed. fiber reinforced self-consolidating mortar (frscm) was developed by optimizing the micromechanical parameters, which control composite properties in the hardened s...

Improved autogenous healing capacity of concrete using superabsorbent polymers (SAPs) was used as an efficient approach for mitigating damage between steel rebar and self-consolidating (SCC). The results normal (NC) those SCC mixtures were compared. Two SAPs with different particle sizes chemical compositions in the experimental program. Results showed that despite greater reduction effect SAP ...

Nowadays, waste production is increased due to the growth of technology and excessive use of natural resources as well as production of new chemicals, among which the hazardous wastes are no exception of that stabilization and solidification method is one of the hazardous waste management methods through which the waste materials are stabilized and confined. High flexibility for various polluta...

The present study presents the effects of steel fibre aspect ratio on fresh and strength properties self-consolidating concrete (SCC). Steel having three different ratios (50, 65 80) with inclusion rate 0.2%, 0.4%, 0.6%, 0.8%, 1.0% was considered, SCC were investigated. Central composite design (CCD) RSM modeling considered to propose a regression model predict 28-day compressive fibre-reinforc...

Capillary pressure is frequently measured to evaluate the shrinkage performance of concrete but has been limited pressures <100 kPa preventing a better understanding early age factors affecting durability. In this study, high capacity tensiometers (HCTs) were employed for first time investigate behavior concrete. The evolution capillary in Self-Consolidating Concrete (SCC) with and without redu...

This study presents the effect of super absorbent polymer (SAP) as internal curing agent on workability, durability and compressive strength self-consolidating concrete (SCC). In order to estimate efficiency SAP in different conditions ages, electrical resistivity tests have been performed. Homogenous denser microstructure was formed by gradual release water from into pores created SAP. Further...
