Study and experiment analysis of the feasibility of partial replacement of Industrial Waste Glass Powder as Cement in Self Compacting Concrete
TL;DR: In this paper, a partial replacement of cementitious material in self compacting concrete in 5, 10, 15% by glass powder decreases the unit weight and porosity by decreases in water absorption.
Abstract: Cement manufacturing industry is one of the Carbon-di-oxide (CO 2 ) emitting sources to the atmosphere. To reduce this emission the alternative material to be used in the concrete in which the glass is adopted. Glass is an economical and environmental friendly construction material. Glass is non-biodegradable material not suitable for landfill. In this paper partial replacement of cementitious material in self compacting concrete in 5%, 10%, 15%. The replacement of glass powder decreases the unit weight and porosity by decreases in water absorption. The early consumption of alkalis by glass particles helps in reduction of alkali silica reaction. The workability of concrete is determined by using slump test and the crushing strength of aggregate is determined by using impact test. Therefore, the glass powder is used to some extent can replace the cement and contribute the strength development and characteristics of durability.

TL;DR: In this article, the connection of construction sector and circular economy with recycled glass in its center is reviewed, and it is shown that by partially replacing Portland cement or aggregate with recycling glass, on average, up to 19% greenhouse gas and 17% energy consumption reduction as well as major cost savings can be made.
Abstract: As a result of socio-economic growth, major increase in solid waste generation is taking place which can lead to resource depletion and environmental concerns. To address this inefficient cycle of make, use and dispose, the concept of circular economy has recently been proposed that de-linearizes the current relationship between economic growth, environmental degradation and resource consumption thorough its 6Rs (Reuse, Recycle, Redesign, Remanufacture, Reduce, Recover). In the construction sector, currently the production of binding agents and transportation of virgin aggregates is associated with considerable environmental pollution. As a result, major attempts are taking place to substitute such ingredients with more sustainable and potentially cheaper materials. With waste glass having a production of roughly 100 million tons annually, and its low recycling rate of 26%, there is a growing number of studies unlocking its potential as an eco-friendly substitute for Portland cement (with particle size of below $$100\ \upmu \hbox {m}$$
) or fine aggregate (with size of below 4.75 mm) in concrete. As a result, this article intends to review the connection of construction sector and circular economy with recycled glass in its center. Accordingly, by partially replacing cement or aggregate with recycled glass, on average, up to 19% greenhouse gas, and 17% energy consumption reduction as well as major cost savings can be made. Additionally, in technical concrete terms, better fresh properties and fire resistance, as well as lower permeability, and in fine grades, favorable cementitious properties are reported as major benefits of using waste glass as a sustainable construction material.

TL;DR: In this article, waste products from various industries like illuminate sludge and glass bottle powder used in different dosages as a replacement for fine aggregate and metakaolin used as a cement replacement.
Abstract: Received: 20 December 2019 Accepted: 18 August 2020 Industrial wastes generally pumped into water bodies and soil that would pollute the atmosphere. As a control measure, industrial wastes products utilized as waste building materials. In the present research, waste products from various industries like illuminate sludge and glass bottle powder used in different dosages as a replacement for fine aggregate and metakaolin used as a cement replacement. Split tensile strength and compressive strength of the concrete samples examined for M30 grade. Fine aggregate is substituted by glass bottle powder (i.e. 10 to 40%) and illuminate sludge (i.e. 10 to 30%). Metakaolin substituted for cement replacement (i.e. 4 to 12%). Glass bottle does not pollute the atmosphere, but the disposal of waste glass results wastage of land. Thereby glass bottle powder can be utilized as a cement replacement in the construction industry. Then the metakaolin and illuminate sludge are the waste products from the titanium product. The experiment performed to assess the strength properties by incorporating various industrial wastes in different dosages. Physical tests of all three products have carried out according to the code requirements. Three specimens have been tested for each industrial waste products ratio to examine the tensile and compressive strength of concrete at 7th day, 14th day and 28th day and eventually to cure to achieve the optimum strength of concrete. Addition of these industrial wastes into the concrete showed an outstanding improvement in modulus of rupture, split tensile strength and compressive strength at an early and later ages.
