Larger consumption of natural fine aggregates (NFA) leads to an increase in cost, energy, and negative environmental impact. On the contrary, larger production construction waste results generation recycled aggregate (RFA), which requires safe disposal. The aim study, is hunt for such alternatives, compares mortar mechanical durability properties with without RFA. High strength specimens were produced mix proportion as 1:3 using RFA partial replacement NFA 0%, 25%, 50% 100%. performance all...
Plain concrete’s major two drawbacks are its low tensile strength and high carbon footprint. Joint adding of fibers recycled/waste materials in concrete might assist to resolve these problems. In the present study, a novel technique is planned improve recycled aggregate (RAC) mechanical behavior durability performance by joint incorporation silica fume (SF) nylon (NF). this research paper, different properties samples examined for example flexural strength, compressive split penetration...
Nowadays the excessive amount of waste tire rubber generates serious environmental problems. One alternative ways for its recycling is as filler in cement concrete. Nevertheless, it known recycled materials added to concrete decrease certain mechanical properties due poor adhesion between fillers and matrix. For resolve this problem, ionizing radiation has been used. these reasons, work, specimens were produced with cement, water, rock crushed sand; last was partially substituted by...
This study analyzes the effect of using waste by-products generated in process granite cutting as part granular structure Ultra High Performance Concrete (UHPC). The manufactured concrete has a compressive strength greater than 115 MPa. substitutes 35%, 70% and 100% volume micronized quartz powder (<40 μm) with waste. is an innovative where feasibility from quarries replacement for UHPC been analyzed. results show improvement workability UHPC, all substitution ratios. flexural tensile...
This research aimed to prove the feasibility of producing two types precast elements widely used in construction, such as curbstones and paving blocks, using recycled concrete made with a 50% substitution natural gravel by mixed aggregates significant ceramic content (>30%). In order quality mass elements, different mixes were used: first one was conventional mix provided Prefabricados de Hormigón Pavimentos Páramo S.L., collaborating companies this study, other mixture which wt coarse...
Flat slabs have several advantages such as a reduced and simpler formwork, versatility, easier space partitioning, thus making them an economical efficient structural system. When producing components in series, every detail can lead to significant cost differences. In these cases, optimization is of paramount relevance. This paper reports on the reinforced concrete slabs, presenting case rectangular slab with two clamped adjacent edges simply supported edges. Using yield lines method...
• Polymer concrete with synthetic waste polymers was elaborated. Effects of gamma radiation and particulate concentration were studied. Compressive strength improved up to 34% respect non-irradiated without particles. Improvement 17% on the compressive modulus elasticity obtained. Simulation using finite elements. In this work, effects polymer particles mechanical properties polyester mortars Control mortar elaborated resin (20%), silica sand (80%). This last partially substituted by each...
