“…The compressive strength test was carried out on the standard size specimen cubes in water binder ratio as 0.45 and 0.5. From the results it is found that the maximum compressive strength of concrete is achieved by using Alccofine 10% and Fly Ash 30% [12]. The compressive strength of concrete with blend containing 59% Cement 15% Metakaolin and 26% Alccofine has achieved maximum packing density and also the flexural strength of the beam has increased with the increases in the percentage of Alccofine [13].…”

In the modern era, many research works are going on throughout the world for finding suitable cementitious material for the replacement of cement since it causes environmental pollution. In this order Fly ash, Silica fume, GGBS, Metakaolin, Micro materials, Quartz powder, etc. are tried out for replacing partially or fully the cement in concrete. A new ultrafine material called Alccofine (AF) which is manufactured from glass wastes is tried out for replacing partially in this research. Compressive strength is one of the important properties of cement. Strength tests are not made on neat cement paste because of difficulties of excessive shrinkage and subsequent cracking of neat cement. Cement mortar of 1:3 mix proportion is used to cast the cubes having an area of 50 cm2 are used for the determination of compressive strength of cement as per IS: 4031-1988 (Part-6). The graded Indian Standard sand (Ennore Sand -ES) confirming to IS: 650-1991 is used for preparing the cubes. In the same mix proportion, the same size cubes are cast with the River Sand (RS) to study the difference of the compressive strength between the Indian standard sand and river sand. Ordinary Portland cement (OPC) and Portland Pozzolana Cements (PPC) are used. The present study is the influence of Alccofine on cement mortar cubes by replacing the cement by Alccofine with various proportions like 5%, 10%, 15%, 20% were cast and tested in the laboratory as per Indian Standard 4301-1988 (Part-6) and the results were analysed and presented in the form of charts and graphs. It is observed that the early age strength is obtained for all the combinations but 10 percent of Alccofine yields more strength than other dosages. Doi: 10.28991/esj-2021-01265 Full Text: PDF

“…The strength enhancement was more with metakaolin in concrete compared to illuminate sludge and glass bottle powder at 7, 14 and 28 days for M30 grade of concrete. The CS of concrete was increased by filling of micropores with metakaolin, glass bottle powder and illuminate sludge powder at an early and later age [18][19][20].…”

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.

“…The material is now being used in a number of major public and private projects. Alccofine has been studied by a number of researchers (6) and (7) who have found it to be an effective pozzolanic substance. Alccofine was found to increase concrete qualities, including resistance to acidic environments, sulfate attack, and chloride ion penetration (8) .…”

Objectives: To evaluate the strength and durability behaviour of concrete specimens that have been reinforced with micro reinforcements made of polypropylene fibers and microfillers and nanofillers such as alccofine and nanosilica, respectively. Methods: The concrete samples were made to achieve a targeted strength of 33 MPa. In this experiment, polypropylene fibers were added to the concrete mix in volume fractions of 0%, 1%, 0.2%, 0.3%, and 0.4%, with the optimum percentages of alccofine (15%) and nanosilica (1%). Concrete mixes with and without PP fibers were evaluated for their mechanical properties, such as compressive strength, elastic modulus, and flexural strength and also looked at several durability characteristics, including acid resistance, porosity, sorptivity, and water absorption. The proper instrumentation has been used to make the measurements related to the experimental parameters. Findings: After the introduction of Alccofine, Nanosilica, and Polypropylene fibers, the following properties have been improved: compressive strength, elasticity modulus, flexural strength, water absorption, porosity, sorptivity, and acid resistance. Adding polypropylene fibers increased the compressive strength of cubes and cylinders by up to 15.15 and 14.87 percent, respectively. It also increased flexural strength by up to 10.47% and elasticity modulus by up to 14.35%. Novelty: The novel material, comprising polypropylene fibers, significantly enhances the mechanical and durability characteristics of concrete, enabling the concrete to avoid brittle and rapid failure and instead experience a more ductile failure that enhances the durability and serviceability of the concrete.
