Abstract

Concrete is a very important construction material and has good compressive properties. According to its mass, concrete is divided into ordinary concrete and lightweight concrete. Light weight concrete is 1000-2000 kg/m3. In high construction projects the use of lightweight concrete can reduce the mass of the building itself. The latest innovation in lightweight concrete is the addition of kaolin as a cement substitute. Kaolin is a clay or clay mineral that contains a lot of aluminum silica. Stryofoam is one of the materials that can be used in lightweight concrete mixes. The use of kaolin and styrofoam waste is sought to support construction materials that are more environmentally friendly. The purpose of this study was to determine the effect of the addition of kaolin on compressive strength so that it can be used as an admixture in lightweight concrete. The results showed that the weight of concrete mixed with 5%, 10%, 15% kaolin and 60% Styrofoam at the age of 28 days was 1836 kg/m³, 1845 kg/m³, 1852 kg/m³. The average compressive strength for the kaolin variants 5%, 10%, 15% were 8.28 MPa, 8.46 MPa, 10.11 MPa. Based on this it was concluded that concrete using a mixture of kaolin and 60% stryofoam can be used in light construction. Because the weight of the lightweight concrete tested was lower than normal concrete and met the specified requirements, namely the specific gravity of the resulting concrete was in the range of 1000-2000 kg/m³.

Abstract

ABSTRACT  Geopolymer is an inorganic polymer material which is rich in silica and alumina and undergoes a polymerization process. Geopolymer concrete is an innovative concrete by replacing some cement binders with industrial waste such as fly ash. In addition, the manufacture of foam concrete is widely used in industrial building construction, especially in the walls of earthquake buildings and energy-efficient buildings. Geopolymer foam concrete is a modification of geopolymer concrete with foam concrete. Geopolymer foam concrete is made by combining a geopolymer mixture in the form of a 14 Molar solution of NaOH and Na2SiO3 as an activator with a ratio of 2.5 and fly ash as a precursor, then adding foam formed from a foaming agent and water with a ratio of 1:20, 1:30, 1:40. The quality of the foam used in the mix for making concrete affects the specific gravity, compressive strength and durability of geopolymer foam concrete. The purpose of this study was to determine the structural ability of geopolymer foam concrete against environmental conditions exposed to sulfate by using several variations in the ratio of foaming agent and water. The results of the endurance test showed that the specimen after being exposed to sulfuric acid for 56 days had a decrease in the mass of the test object for the ratios of foaming agent and water 1:20, 1:30, 1:40 which were 7.64%, 7.90% and 8.56 %. The ratio of foaming agent and water in the manufacture of smaller foam indicates better specific gravity, compressive strength and durability against sulfate attack.

Abstract

Self-Compacting Concrete (SCC) is a type of concrete capable of compacting itself without the use of vibrators, characterized by a high slump and the ability to flow under its own weight to fill formwork completely without segregation, thereby simplifying the construction process. The materials used to produce SCC include fine aggregates, coarse aggregates, water, and cement, combined with admixtures in the form of superplasticizers. The superplasticizers added in this study were Consol SG at 0.3% and Consol N11 LN at variations of 0.6%, 1.4%, and 2%. Workability test results for SCC indicated slump flow values of 39.17 cm for 0.6% SCC, 56.72 cm for 1.4% SCC, and 61.24 cm for 2% SCC. L-Shape Box tests yielded results of 0.067 for 0.6% SCC, 0.949 for 1.4% SCC, and 0.987 for 2% SCC. The V-Funnel Test produced times of 32 seconds for 0.6% SCC, 11 seconds for 1.4% SCC, and 8 seconds for 2% SCC. Compressive strength testing of normal concrete showed values of 22.36 MPa at 7 days, 28.79 MPa at 14 days, and 35.28 MPa at 28 days. For SCC with 0.6% admixture, compressive strengths were 23.85 MPa at 7 days, 29.58 MPa at 14 days, and 36.17 MPa at 28 days. SCC with 1.4% admixture yielded compressive strengths of 25.27 MPa at 7 days, 30.16 MPa at 14 days, and 38.26 MPa at 28 days. SCC with 2% admixture reached compressive strengths of 28.04 MPa at 7 days, 33.62 MPa at 14 days, and 38.63 MPa at 28 days. Water absorption tests at 28 days showed values of 120 g for normal concrete, 110 g for SCC with 0.6% admixture, 100 g for SCC with 1.4% admixture, and 110 g for SCC with 2% admixture.

Abstract

Increasing cement consumption in line with growing construction activities has led to higher building costs and rising carbon dioxide (CO2) emissions, both of which contribute to global warming. One potential alternative material is carbide welding waste, a residue generated from welding processes that is often underutilized and frequently becomes waste with the potential to pollute the environment. This study aims to analyze the effect of using carbide welding waste as a partial cement substitute on the physical and mechanical properties of concrete, particularly its water absorption (absorptivity) and compressive strength. The method used is an experimental approach with substitution variations of 6%, 9%, and 12% of carbide welding waste relative to the cement weight. The test results show that these substitution percentages produce different effects on the characteristics of the concrete. A 9% substitution provides the most optimal outcome, with a compressive strength of 28.95 MPa and the lowest absorption value of 2.4417%. These values are superior to those of normal concrete without substitution, which has a compressive strength of 25.64 MPa and an absorption value of 2.7001%. At 6% substitution, the compressive strength reaches 26.74 MPa with an absorption value of 2.5481%, while at 12% substitution, concrete quality declines, with compressive strength dropping to only 22.50 MPa and absorption increasing to 3.2416%. The findings demonstrate that carbide welding waste can be used as a partial cement substitute, with the optimal percentage being 9%.
