In the research glass from municipal solid waste is prepared in two different ways: 1) washed under running water, dried, and milled in a ball mill (referred to as washed waste glass powder); 2) Ultra-lightweight cement concrete (ULCC) has recently been introduced as an emerging construction material, which can be defined as low density (<1450 kg/m3) with high compressive strength (≥60 MPa) cementitious composite [14]. L. Infra-Lightweight concrete opens new ways to “Baukultur Shrinkage of lightweight concrete in comparison with that of normal weight concrete of similar compressive strength. El Madawy 2 , Sang-Yeop Chung 3, *, Pawel Sikora 1,4 This paper aims to investigate the feasibility of the incorporation of nanosilica (NS) in ultra-lightweight foamed concrete (ULFC), with an oven-dry density of 350 kg/m ³ , in regard to its fresh The present study aims to characterize the constitutive models of a novel ultra-lightweight low-carbon LC 3 cement composite (ULCC-LC 3) under monotonic uniaxial compression and tension tests. g. with ultra-lightweight concrete were prepared at densities of 150, 200, 250 and 400 kg/m3. Its intended use as monolithic building envelope brings new opportunities in building physics, by merging characteristics of both heavyweight and lightweight construction types [11]. 3—Applications of high-performance lightweight concrete, p. The paste matrix of this material has a cellular microstructure, and bulk performance is readily affected by the inclusion of fines. 5–1. A predesigned mineral precursor resulted from industrial by-products is used as the raw material for alkali activation and NaOH with a low concentration of 2–3 M is used as the alkali activator, A type of ultra lightweight cement composite (ULCC) was developed [9] to tailor the offshore structural applications in the Arctic areas, in particular for offshore floating structures and liquefied natural gas (LNG) storage tanks. 0–87. In recent years, EPS concrete as structural or semi-structural elements is widely used in bridge barriers, sandwich wall panels, load bearing concrete blocks, curtain walls, etc [10], [11], [12]. The hydrophobic nature and very low-density of EPS beads can be a disadvantage when used in concrete because Therefore, the acoustic absorption and thermal insulation of ultra-lightweight Miscanthus concrete (ULMC) is investigated using two different kinds of Miscanthus fibers. 3 MPa have been developed for buildings and offshore An increase in density will occur with the rise of the compressive strengths of the lightweight aggregate concrete. First, with a typical mix, the transfer of moisture into and out of the lightweight aggregate particle prevents the buildup of a high w/c The inferior mechanical properties and durability of conventional lightweight concrete restrict its wider application. 12 W/(m K); and moderate mechanical properties, with a 28-day compressive strength of about 10–12 N/mm2. Our lightweight concrete products are revolutionizing the future of construction. Table 3. The aesthetic, surface characteristics, and weight savings are what make our GFRC panels ideal for The ultra-lightweight cement composite (ULCC) has been developed and applied in the reinforced flat slabs and DSC slabs and shells for building and offshore constructions. Mix ID This research investigates the impact of waste glass powder, high-frequency ultrasonics (HFUS) dispersion, and liquid glass treatment on aluminum-based ultra-lightweight concrete. 36 CHAPTER 9—ENHANCED PERFORMANCE DUE The ultra-lightweight concrete with foam glass aggregate reaches high resistance to high temperatures up to 1000 °C as well as a large thermal attenuation over the height of the specimen. The average 28-days cylinder compressive Lightweight Concrete Solutions is an industry leader in environmentally friendly concrete technologies using post-consumer recycled materials. Its The main benefit of lightweight concrete is that the lighter weight of this type of concrete reduces the dead load of the structures, resulting in smaller sizes of vertical Lightweight concrete has a history of more than two-thousand years and its technical development is still proceeding. 15–0. ASTM, West Conshohocken, PA, 2017. 59 cubic foot. Based on the existing information, the excessive use of natural aggregates has Ultra-high-performance concrete (UHPC) has high mechanical strengths and durability, but its density and carbon footprint are usually high. Ultra-lightweight. 66 cu. The fine aggregate is standard medium sand (S) with a particle size range of 0. Inside or Outside Use. In the terms of building envelope and thermal insulation field, EPS concrete has more advantages than other The material studied in the following is a structural lightweight concrete with an ultra-high-performance matrix and expanded glass as a lightweight aggregate. Our proprietary concrete is less than half the weight of regular concrete while maintaining strength, durability and raw Engineered cementitious composite (ECC), developed based on micromechanical theory by Li [1] and incorporating PVA fibers, represents a distinctive high-performance fiber-reinforced concrete material, boasting an ultimate strain capacity over 3%. 1 Materials 2. tws. Other main advantages include the extremely low weight, which results in minimal static load on the structures due to its own weight, and the use of waste AbstractThe aim of this study is to develop an eco-friendly lightweight concrete that contains recycled expanded glass aggregate (EGA) and pine resin (PR) and to contribute to sustainable solutions for energy consumption, energy efficiency, and waste Despite intensive research works had been done to improve the bubble stability through various stabilizing foaming technologies (surfactant, nano colloidal particles, hydrogel, etc. , high-filled open-cut tunnel [1] and urban underground space backfilling [2]) because it has controlled density, as well as good thermal and sound insulation properties [3, 4]. Google Scholar [51] B. VOC Rating: 0 g/L Shelf Life: 1 year in original unopened container The developed ultra-lightweight concrete, with a dry density of about 650–700 kg/m3, shows excellent thermal properties, with a thermal conductivity of about 0.
