... As per a report of 1981 which has been published in Britain, it has been stated that human hairs can be used in the form of fibre reinforcement in roofing where precaste concrete is used specially in houses with lower cost, Free, restrained and drying shrinkage of cement mortar composites reinforced with vegetable fibre. addition, densities of the OPC/CHA sandcrete blocks were also determined. Sign Up to The Constructor to ask questions, answer questions, write articles, and connect with other people. Grade of cement (43/53) 2.) The water to binder ratio of 0.5 was … The current experimental study analyses the prospects of working on human hair as a fiber reinforcement substance by studying and testing on concrete cubes in compression testing machine so as to scan the compressive strength of plain cement concrete with fiber reinforced concrete containing human hair in different proportions like 1%, 1.5%, 2% and 8% by weight of cement for the curing period of 7, 14 and 28 days as per the clauses laid in IS 456:2000 (Indian standard Plain and Reinforced Concrete-Code of Practice). In particular, alfa fibre, which is produced in Mediterranean area, is herein considered. Testing procedure. ing a higher compressive strength mortar than necessary” is intend-ed to prevent the specifier from automatically selecting the stron-gest mortar type in the table, i.e., formerly Type A1, now Type M mortars. three different percentages of nylon fiber were added in the mixture during the samples preparation period which consists of 0.5%, 1.5% and 2.5% by total weight of cement based mortar. The coconut fibres were added in different percentages (1 wt%, 2.5% and 5 wt%) and three Aspect Ratios (0.714, 7.143 and 14.286), to examine the effect of a monodisperse addition. In, Cement mortar is a broadly used construction material. Volume of sand in cubic foot = 1.064 ×35.3147 = 37.57 Cuft. Assistant Professor, Department of Civil Engineering, Assistant Professor, Department of Civil Engineering, University of Engi, Lecturer, Department of Civil Engineering, Assistant Resident Engineer, East Consultants D.I.Khan, Pakistan, Ibrar Ahmad, Qurtuba University of science & IT, D.I Khan, Density: Density of coconut fibers ranges from 0.67-1 g/cm. Most of this by product material is currently dumped in landfills, thus creating a threat to the environment. thnks in advance. al., "Free, restrained and drying shrinkage of cement mortar In this paper, results of an experimental study have been presented to determine the effect of randomly oriented hair fiber on mechanical properties of fly ash based hollow block. I. Ahmad et al. Strength of cement is the most important of all the cement properties. Coconut fibres are by-products from, An investigation has been carried out to study the effect of nylon fiber on the mechanical properties of cement based mortar after receiving large quantities of nylon waste. Lime comes from Old English lim "sticky substance, birdlime, mortar, cement, gluten", and is related to Latin limus "slime, mud, mire", and linere "to smear". Mortar is a combination of cement, sand mixed with water. Better terminology would be “do not select a mortar type with a higher portland cement content than necessary.” The mor- The study therefore arrived at an optimum replacement level of 10%. use, after which it is again thrown away in the solid waste. All samples using constant water-cement ratio of 0.63 and, Laboratory experiments were conducted to investigate the effects of recycled plastic (RP) waste fibers on the flexural strength, flexural toughness and plastic shrinkage cracking characteristics of Portland cement mortar. The results indicate that the incorporation of PET fibres significantly improve the flexural strength of mortars with a major improvement in mortar toughness. © 2009-2020 The Constructor. Water Cement Ratio in Mortar: Mortar may be defined as a paste (capable of setting and hardening) obtained by adding water to a mixture of fine aggregates such as sand and binding materials, e.g., clay, gypsum, lime, or cement or their combinations. For 1 cubic meter of 1:4 mortar you need 1.064 cubic meter ( 37.57 cft ) of sand. setting time, heat of hydration and total shrinkage), compressive strength and durability indicators (water absorption, porosity, acid attack and chloride ions di usion) was carried out on mortar containing 10%, 15% and 20% of GP as partial substitution to cement (CEM I 42.5 R) in the short and Is followed by a review of the OPC/CHA sandcrete blocks were also determined development...
