Abstract The production of cement results in a significant amount of energy consumption and CO2 emissions, which are major contributors to environmental pollution. Researchers have developed a ternary blended mix concrete to address these concerns by partially substituting cement with a combination of lime sludge (LS) and wollastonite powder (WP). This study investigated the mechanical properties (compressive strength, spilt tensile strength, and flexural strength) of a ternary blended concrete mix with a grade of M30. 180 specimens, including 60 cubes, 60 cylinders, and 60 prisms, were prepared for testing. The blended concrete mix was produced using different percentages of cement replacement by LS (5%, 10%, 15%) and WP (10%, 15%, 20%). The compressive strength for the ternary mix at 10% LS and 15% WP was 44.78% higher than the conventional mix, the flexural strength ternary mix at 10% LS and 15% WP was 25.46% higher than the conventional mix, and spilt tensile strength ternary mix at 10% LS, and 15% WP was 27.30% higher than the conventional mix at 28 days and trend is almost same for 7,56 and 90 days . The results showed that a ternary mix containing 75% cement, 10% LS, and 15% WP exhibited the best mechanical properties.

The present study is focused on the compressive strength, water retention, and workability by varying the percentage of poly ethylene glycol 200 and liquid paraffin wax from 0% to 1% by weight of cement for self‐compacting concrete and compares it with conventional SCC. Percentages of 0.1%, 0.5%, and 1% (in proportion to the weight of cement) were adopted in the study. The comparison was done in a grade concrete and with cases such as indoor curing and water‐based curing. Slump‐flow test and V‐funnel tests were carried out on the fresh concrete to evaluate the workability of concrete. Concrete weight loss with time is evaluated to determine the water retention capacity. Compressive strength of cube specimens was conducted at the end of 7 and 28 days of curing. The durability of the concrete was assessed by immersing the concrete specimens in acids. The fresh properties were satisfied according to EFNARC specifications. Based on the weight loss percentage and satisfaction of compressive strength, the dosage of a self‐curing compound was determined. XRD analysis of the concrete was also performed on the concrete specimens.

In present scenario concrete is highly consumed material in construction field due to its advantages, because of this the natural resources are depleting day by day at an alarming rate and there is an immediate need for finding alternate materials to the natural materials in concrete. In this paper an effort is made to find alternate partial replacement materials for cement and fine aggregate (FA). M40 grade concrete is adopted and the cement was replaced with egg shell powder with different percentages of 5%, 10% and 15%. The optimum percentage egg shell powder (ESP) is obtained at 10%. At optimum ESP the FA is replaced with Quarry Dust (QD) with percentages of 25%, 50%and75%. The maximum strength properties are obtained at 10% ESP and 50% QD and the concrete is also durable at 10% ESP and 50% QD with Water Cement Ratio is 0.38.
