Sugarcane bagasse and rice husk ash pozzolans: Cement strength and corrosion effects when using saltwater

Industrial waste productions are increased these days, which is causing grief to the environment. Hence it is necessary to cut down the waste generation or reuse the waste. It is needed to utilize the waste to reduce environment damage. It is known that ashes produced from the industries can be used in construction. Ashes like fly ash can successfully replaces the cement showing good results. Researchers are finding the new ways to use ashes in production of cement. Now a days cement manufactures adulterates the cement with pozzolanic material like fly ash, rice husk ash, sugarcane bagasse ash etc. Using these product in concrete, they not only reduces the pollution but also lower the price effectively. If these fillers added in proportion it enhances the properties of concrete like workability, strength, water absorption, permeability etc. considerably. This review paper represents the properties of concrete when cement gets partially replaced by sugarcane bagasse ash, fly ash and rice husk ash. This paper primarily concentrates on the properties like durability and strength when cement concrete contain fillers in it. It also considers the non-destructive tests which are performed.

Cement Strength

Designing a slurry with adequate strength resistance is a major objective in oil and gas completion job. Various studies and research confirms that Compressive Strength (CS) and Shear Bond Strength (SBS) are two parameter which is imperative in describing cement strength in well cementing job. This experimental study introduces a Rice Husk Ash (RHA), an alternative cement additive derived from organic waste. RHA rich in silicon oxide (SiO2) and has a pozzolanic reaction, which is correlated in enhancing cement strength. Serial cement samples with various concentration of RHA were prepared to investigate the effect of RHA concentration to CS and SBS. All samples were then Dried for 24 hours in room condition after completing mixing and molding process. A Biaxial Loading test was then performed to all samples to determine the CS and SBS values by using hydraulic press apparatus. Results from the loading test generally indicate an enhancement of CS and SBS for samples with 31%, 32%, 33%, and 34% RHA. An indication of higher CS and SBS is not found for sample with 35% RHA, comparing with 34% RHA. Thus, 34% RHA is the optimum concentration for theses study, which yield 1312. psi of CS and 158.16 psi of SBS. Through this study, there is an opportunity for transforming waste material into alternative additive with higher economic value.

Pozzolanic Properties

Study ini membandingkan kuat hancur, berat volume antara beton ringan dengan beton dengan mengganti sebagian semen (PC) dengan limbah pertanian. Limbah pertanian yang dimaksud adalah sekam padi dan ampas tebu. Penggunaan limbah pertanian tersebut sebaga material pengganti semen dikarenakan mempunyai sifat pozzolan yang cukup tinggi. Pemakaian limbah pertanian ini dengan membakar ampas tebu dan sekam padi dengan suhu tertentu sehingga menjadi abu. Limbah tebu diambil dari Pabrik Gula Prajekan Bondowoso, dibakar dengan suhu 8000C selama 8 jam. Limbah Padi diambil dari limbah Pabrik Padi di Kalisat Jember, dibakar dengan suhu 8500C selama 45 menit. Kandungan silika dari hasil pembakaran tersebut masing-masing sebesar 59,5% dan 79,5% . Prosentase pengganti sebagian PC sebesar 5%, 10%, 15% dan 20%, dengan perbandingan campuran abu ampas tebu (AAT) dan abu sekam padi (ASP) adalah 1:1. Pengujian dilakukan pada umur 28 hari dengan bentuk benda uji silender berukuran 10x20 cm. Hasil kuat hancur tertinggi pada benda uji dengan subsitusi PC sebesar 5% dan berat volume yang terendah pada benda uji dengan pengantian semen sebesar 20%. Effect of Cement Substitution with Agricultural Waste on Lightweight Structural ConcreteThis study compares the shattering strength, volume weight between lightweight concrete and concrete by replacing part of the Portland cement (PC) with agricultural waste. The agricultural waste in question is rice husk and sugarcane bagasse. The use of agricultural waste is as a substitute for cement because it has quite high pozzolanic properties. Use of this agricultural waste by burning sugarcane bagasse and rice husk with a certain temperature so that it becomes ash. Sugarcane waste is taken from Bondowoso Prajekan Sugar Mill, burned at 8000C for 8 hours. Rice waste is taken from the rice factory waste in Kalisat Jember, burned at 8500C for 45 minutes. The silica content of the combustion products was 59.5% and 79.5%, respectively. The percentage of partial PC replacement is 5%, 10%, 15%, and 20%, with a ratio of bagasse ash (BA) to rice husk ash (RHA) is 1: 1. The test was carried out at 28 days in the form of a 10 x 20 cm slender test object. The highest yield of crushing strength in specimens with PC substitution of 5% and the lowest volume weight in specimens with cement replacement of 20%.
