The rising cost of concrete production due to the global recession in world economy caused by the COVID-19 pandemic and the greenhouse gases emitted in the production of cement has necessitated the need for alternative materials for cement. In this study, bamboo strips and steel rebars were used as reinforcements in a ternary blended concrete to determine their strength properties. In alignment with standard requirements for testing, concrete specimens were tested at curing ages of 7, 14 and 28 days for compressive, splitting tensile and flexural strengths. The morphological and bond characteristics of the bamboo were determined through the Scanning Electron Microscopy (SEM) and Fourier Transform Infra-Red Spectroscopy (FTIR), respectively; while its tensile strength was determined and compared with that of steel reinforcement. These results showed that bamboo is ductile and has stretching vibrational spectrum. The combinations of quarry dust, river sand, Rice Husk Ash (RHA) and Guinea Corn Husk Ash (GCHA) yielded compressive and split tensile strengths of 20.4 N/mm 2 and 2.18 N/mm 2 , respectively. Concrete with 50 % river sand and 50 % quarry dust performed better in flexure for both Bamboo Reinforced Concrete (BRC) and Steel Reinforced Concrete (SRC) at 28 days with strengths of 12.75 N/mm 2 and 22.49 N/mm 2 , respectively. Therefore, bamboo, quarry dust, rice husk and guinea corn husk ash can be used for reinforced concrete production.

“…In addition it was due to the reactive RHA pozzolanic reaction. Whereas for samples with SP mix 50% the strength slightly reduced by 7.5% this may be because of after 40% replacement by RHA it works as filler only and not took part forming CSH gel [23]. Hence it is evidence that samples with SP possess high strength of enhanced concrete.…”

In this research work, the effect of rice husk ash (RHA) along with and without superplasticizer (SP) on the properties of concrete was investigated. The good workability and compaction is key parameter for strength and durability of concrete, and it may achieved by adding SP in to the concrete. In India RHA is available in huge quantity. It is byproduct of agriculture. In present research ordinary portland cement (OPC) was replaced by 10 to 50% RHA. The fresh properties as workability and hardened properties of concrete as compressive strength were examined. For durability test water absorption, acid attack and sulphate attack tests were conducted.The test results show that at 10%RHA with SP the maximum strength of concrete was attained with respect to control concrete mix (CM). The satisfactory test results were shown for durability and strength. Such kind of blend concrete is more efficient to enhance the properties of concrete which reduce the consumption of cement. The utilization of agricultural byproduct makes concrete sustainable and reduce environmental problems.

“…Whereas the replacement of cement increased like 40% the strength shows decreased. This was happened due to the maximum utilization of Ca(OH) 2 up to 30% replacement of cement by SCM and after that the SCM behaves like filler or inert material [32].…”

The strength and modulus of elasticity (E) of concrete are an important aspect for design. Hence, to achieve this parameter use of industrial and agricultural byproduct can be used in concrete as partial replacement of cement. For such new triple blend concrete is needed to determine the compressive strength and ultrasonic pulse velocity (UPV), modulus of elasticity (E) and microstructure of concrete. To this objective, various mixtures of concrete were produced by replacing 20%, 30% and 40% of cement with FA and RHA blends. The modulus of elasticity was determined by various formulations such as UPV, IS and ACI. The modulus of elasticity, compressive strength and durability of triple blend concrete were improved at 20% cement replacement. As a results the concrete makes sustainable with this new triple blend. KeywordsStrength • Modulus of elasticity • Concrete • Fly ash • Rice husk ash
