چکیده

The concept of self-healing concrete is becoming more necessary as sustainability in construction desirable. Amongst the current solutions this technology are autogenous, chemical, and bacterial self-healing. It paramount that secondary raw materials be used production selfhealing a form sustainable solution. Therefore, paper, admixture “Betocrete-CP-360-WP”, which crystallizing waterproofing with hydrophobic effect 100% recyclable, has been its on physical, mechanical properties concrete, well capabilities have determined. According to obtained results, crystalline additive “Betocrete-CP-360-WP” no density slightly increases amount entrained air mix. However, it does decrease workability mixture could prove problematic transportation site or concreting general. Also, mix, 60% reduction compressive strength after one day hardening estimated, but 7 28 days, attained within ranges control samples. In addition, containing Betocrete-CP360-WP was 30% less water permeable compared efficiency determined by flow test through formed crack (approximately 0.35 mm wide). This done gluing plastic pipe top cracked specimens maintaining constant pressure pipe. experiment continued for calculated from differences passed before healing 7, 14, 21 days process. After test, cracks recycled dust were completely healed, while not.

Effect of Mineral Admixture on Properties of Self Compacting Concrete

In this study, the benefits of limestone powder (LP) and marble powder (MP) as partial replacement of Portland cement are established. Furthermore, LP and MP are used directly without attempting any additional processing in the production of selfcompacting concrete (SCC). The water to binder ratio is maintained at 0.33 for all mixtures. The examined properties include workability, compressive s...

Investigating properties of fresh and hardened self-compacting concrete made of recycled aggregates

Self-compacting concrete is a new high performance concrete with high ductility and segregation resistance. In recent years, construction material manufacturers have focused their attention on lightweight concrete and have strived to use lightweight concrete, if possible, in load-bearing parts of buildings. Concrete with both self-compacting and lightweight properties is favourable in this cont...

Assessing relationships among properties of demolished concrete, recycled aggregate and recycled aggregate concrete using regression analysis.

Recycled demolished concrete (DC) as recycled aggregate (RA) and recycled aggregate concrete (RAC) is generally suitable for most construction applications. Low-grade applications, including sub-base and roadwork, have been implemented in many countries; however, higher-grade activities are rarely considered. This paper examines relationships among DC characteristics, properties of their RA and...
