نویسندگان

چکیده

Statistical methods such as Scheffe’s and Osadebe’s models are commonly employed for the optimization of concrete properties. Despite their prediction suitability, attention is drawn to drawback. Ibearugbulem’s model has been developed address these shortcomings. In this study, method was formulate a mathematical strength-optimization nanostructured cassava peel ash (NCPA)-cement composite. The variation 28 days compressive strength initial final setting time NCPA-concrete evaluated. Based on establishment spatial domain each mixture variable, response function expressed multivariable proportions constituent materials. Applying variational approach, within specified optimized. There were 51 observation points. Twenty-six points used remaining twenty-five test adequacy formulated model. odd serial number ones selected formulation even numbers testing Fisher’s statistical tool in analysis calculated value fisher 1.11 lower than 1.94 derived from f-distribution table. This result proved that there no significant difference between laboratory values modeled at 95% confidence level. shows reliable, safe, recommended production.

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...

The Influence of Pet Fibers on the Properties of Fresh and Hardened Concrete

There is a worldwide interest in using fibers of different types in concrete mixtures. In this regard, as the use of PET fibers has gradually increased during the last decade, this study aims to investigate the effects of PET fibers on the mechanical properties of hardened concrete and the workability of fresh concrete. To this end, different contents of PET fibers (PC= %0, %0.5, %1 and %1.5) a...

Prediction of mechanical and fresh properties of self-consolidating concrete (SCC) using multi-objective genetic algorithm (MOGA)

Compressive strength and concrete slump are the most important required parameters for design, depending on many factors such as concrete mix design, concrete material, experimental cases, tester skills, experimental errors etc. Since many of these factors are unknown, and no specific and relatively accurate formulation can be found for strength and slump, therefore, the concrete properties ca...

An Experimental Study of Effects of Superplasticizer on Fresh and Hardened Properties of Concrete

This paper presents the results of an experimental research on the workability and compressive strength of ordinary and standard concrete. Superplasticizers are commonly known as High Range Water Reducers (HRWRs) because it permits low water cement ratio as well as the workability also affected. In this paper the properties of concrete mixtures with three different dosages of superplasticizers ...
