“…Authors in a study 25 observed improvement in concrete mechanical properties when joint addition of WSA with metakaolin was utilized to replace cement along with nylon fibers. Concrete mechancial strength was improved 26 significantly with 20% substitutions of cement with WSA, similar results were noted by researchers. 27 Fine aggregate like sand could be also 28 replaced with waste materials like waste marble powder (WMP).…”

In developing countries, cement is one of the most consumed materials, which leads to a huge quantity of emission of carbon dioxide (CO 2 ) gas into the atmosphere. Cement could be replaced with materials that have pozzolanic properties and filler ability such as wheat straw ash (WSA). The focus of the present research is to substitute cement with WSA and fine aggregate with waste marble powder (WMP) in different doses ranging from 0% to 20% and 0% to 30% with 1.5% hooked end steel fibers in concrete. To evaluate different characteristics of concrete made with WSA, WMP and steel fibers, tests such as compressive, split tensile and flexural strength, sorptivity, water absorption and microstructural analysis were performed, From the lab results, it was revealed that the optimum dosage for concrete with improved properties was 15% WSA, 30% WMP, and 1.5% steel fibers. An improvement of 43.5%, 59%, and 45.96% was observed in compressive, split tensile, and flexural strength. Water absorption and sorptivity were reduced by 15.9% and 29% with the addition of WSA

“…Compressive strength was conducted after the curing time period of 7 and 28days this test show the strength of material to with stand against the application of load in compression test load is applied to cube until the rapture of cube takes place [9]. The compressive strength goes on decreasing with increasing % of partially replacement of cement with SCBA and RHA.…”

“…The compressive strength goes on decreasing with increasing % of partially replacement of cement with SCBA and RHA. The maximum compressive strength was absorbed at 5% replacement at 28days curing and minimum was at 15% because of the porous nature of rice husk there is minimum resistance to applied load [9] or because of the use of a high quantity of agricultural waste put impact on water penetration in concrete which results in production of lesser amount of calcium hydroxide [10]. The results have been plotted in Figure .3.…”

In current development of cities the key role played as binding material in construction work is by cement but where there are so many benefits some drawbacks are also there as in manufacturing of cement great amount of CO2 is emitted which contribute enough to pollute the environment so researchers are looking for other materials bearing same properties like cement and which are environmental friendly material. So in this research cement is being replaced by rice husk ash and sugarcane bagasse ash which are agricultural and industrial waste. The cement was replaced with varying percentile i.e., 0%, 5%, 10% and 15% of each of material in mortar. Flowability, compressive strength test results shows that the flowability of mortar reduced with the rise in limited substitution of RHA and SCBA when the w/b ratio was kept constant as 0.50. The Compressive strength of mortar cubes were evaluated after the curing of 7 and 28days and it was found that at each specified day shows that up to 10% substitution results are up to expectation but results sharply goes down at 15% substitution but at 5% replacement for each of material on 28th day curing gives highest results of compressive strength. furnace test was conducted on different elevated temperatures I.e., 400 O C, 600 O C, 800 O C to check the load bearing strength of cube after subjected to raised temperature .the cube at 28days curing was exposed to elevated temperature to check compressive strength and found that at 5% replacement its compressive strength have higher value.

“…The important mechanical properties of typical pervious concrete, such as compressive strength, flexural strength, split tensile strength, porosity, permeability, and density or unit weight, are shown in Table 1. According to the literature, the unit weight of pervious concrete in the general field is approximately 1500-2000 kg/m 3 [11][12][13][14][15][16][17][18]. This light density is due to the fact that porous concrete has pores ranging from 15 -35% with a permeability of 4.2 mm/sec.…”

This article identifies the potential of East Borneo local aggregates as a material in producing pervious concrete. East Borneo has to import material from another island (Palu / Central Sulawesi), which ends up with a high price in the concrete unit. In addition, high population growth, continual urbanization, rapid infrastructure development have reduced the infiltration area. This problem increases surface runoff, which can involve flooding. Research on the potential of local aggregates for porous concrete materials needs to be carried to reduce this problem. In this study, several coarse aggregates in East Borneo were used: Senoni, Cermin, Suryanata, and Muara Asa aggregates. This material is compared with Palu aggregate, which currently use in East Borneo. The tests such as compressive strength, split tensile strength, and flexural strength were carried out. Results of this research show that the concrete performance varies widely amongst the different aggregates. The compressive strength, flexural strength, and split tensile strength values range from 9.06 MPa to 21.97 MPa, 1.99 MPa to 3.98 MPa, and 1.38 MPa to 2.95 MPa respectively. Overall, Senoni aggregate is found as the best quality compared to other local aggregates. This research provides an overview of East Borneo local materials as infrastructure development to reduce dependence on Palu materials.
