Abstract
Background/Objectives: To develop a self-curing concrete economically. Methods: To make self-curing concrete, natural and chemical admixture were used; samples were cured in room temperature (15-20°c) and outdoor condition (30-35°c). Firstly, samples were divided into fourteen trials with different percentage of wood powder 2%, 4%, 6%, 7% and 8% and polyethylene glycol 400 (PEG400) 0.5%, 1%, 1.5%, 2%, 2.5%. Finally, 6% wood powder was found as optimum trial and again made trials of constant percentage of wood powder (6%) with different combinations of PEG400 (0.5%, 1%, 1.5%, 2% and 2.5%) in room and outdoor temperature. The specimens were cured for 7 and 28 days. Findings: The results show that the uses of wood powder and PEG400 have positive effect on mechanical properties of concrete compared with conventional concrete. Improvements/Applications: A mix of 6% wood powder with 1.5% polyethylene glycol 400 (PEG400) is found optimum and economical for M30 grade of concrete in room temperature but for having a good strength of grade M30 of concrete considering economical point for outdoor temperature a mix of 6% wood powder with 2.5% polyethylene glycol 400 (PEG400) can be effective and optimum. Keywords: Outdoor Temperature, Polyethylene Glycol-400, Room Temperature, Self-Curing Concrete, Wood Powder
Highlights
Concrete is a superior building material with equivalent mixing of aggregate, cement, and water and with or without chemical-mineral and other admixture in the adaptation with the production[1]
This study has divided in two use type of materials, first one with different percentage of (0%, 10%, 15%, 20%) is pre-soggy lightweight aggregate of volume of sand and other type is PEG by weight of cement with percentages of (1%, 2% and 3%) and all tests conducted in three different water cement ratio of 0.5, 0.4 and 0.3 with using different percentages of silica fume 0.0%-15% of weight of cement in 28days and 25c° The best result Shown as two percent of PEG with fifteen percent of lightweight aggregate combined with greater cement content and poorer water cement ratio[8]
All tests conducted in fourteen trials of different percentage of admixtures, for having an accurate result the optimum trial was tested in room temperature and outdoor temperature
Summary
Concrete is a superior building material with equivalent mixing of aggregate (fine and course), cement, and water and with or without chemical-mineral and other admixture in the adaptation with the production[1]. This study has divided in two use type of materials, first one with different percentage of (0%, 10%, 15%, 20%) is pre-soggy lightweight aggregate of volume of sand and other type is PEG by weight of cement with percentages of (1%, 2% and 3%) and all tests conducted in three different water cement ratio of 0.5, 0.4 and 0.3 with using different percentages of silica fume 0.0%-15% of weight of cement in 28days and 25c° The best result Shown as two percent of PEG with fifteen percent of lightweight aggregate combined with greater cement content and poorer water cement ratio[8]. By using Silica fume (up to 15%) Calortopis.G (0.2%, 0.3% and 0.4%), and Cypress (up to 15%) working on hardened and fresh properties of concrete best result was 0. By using Silica fume (up to 15%) Calortopis.G (0.2%, 0.3% and 0.4%), and Cypress (up to 15%) working on hardened and fresh properties of concrete best result was 0. 4% Calortopis.G, Cypress 15% and 15% of Silica fume[9]
