OPTIMIZATION OF SELF-COMPACTING CONCRETE USING RESPONSE SURFACE METHODOLOGY
نویسندگان
چکیده
The development of predicting models is necessary for an easier and more accurate design mix self-compacting concrete. Due to the difficulty test requirements this type concrete, a model useful can be used derive optimum mix. Different mixtures with varying cement, water, superplasticizer content were created using central composite design. A full quadratic was chosen all dependent variables considered such as flowability, passing ability, resistance segregation, 28th-day compressive strength, flexural strength. Water only significant factor that affects rheological properties Mixtures high water show segregation bleeding but yield Surface response interaction profiles are developed help user in modifying their Response surface methodology (RSM) optimum. derived follows, cement 483.72kg, 250kg 1% SCC has desirability 0.812. slump flow 609.22mm (>550mm passing), l-box 0.915 (>0.80 -0.962% which assumed equal zero (<15% 41.79Mpa strength 10.33Mpa passes acceptable strengths. Although mixture content, due requirement rheology. Low ideal limiting bleeding.

Mix Proportioning of High Performance Self-Compacting Concrete using Response Surface Methodology
High performance self compacting concrete (HPSCC) is typically proportioned with mineral and chemical admixtures leading to relatively high material cost. Such cost can be tolerated in high value added applications specially when cost savings can be realized using HPSCC in terms of reduction in size of reinforced concrete members. Efforts are still needed to reduce material cost of HPSCC to gai...

Since Amaranth (AM) is one of the dye compounds which is harmful to human’s life its removal from industrial waste water would reduce their environmental impact and health effect. Copper nanoparticle (CuNP) is a simple and eco-friendly material which can be used to remove this pollutant. In this paper, copper nanoparticles were synthesized, for removal of AM dye. The experiments were designed b...
