“…Pozzolan inclusions such as SCBA in soil cement mixtures can accelerate the curing hydration when pozzolan reacts with calcium hydroxide and water to form secondary calcium hydrate (CSH) along with calcium alumina silica hydrate (CASH). This process containing additional silica and activated cement alumina thus create an alkaline atmosphere that increases the secondary pozzolanic reaction in the treated soil [7]. Previous study indicates that with 20 % of cement replacement with SCBA have unconfined compressive strength (UCS) reaching 387 kPa.…”

“…The massive use of cement during the peat stabilization process contributes to the release of CO2 due to concrete production. Cement is responsible for about 5 to 8 % of global carbon oxide emissions and expected to increase by 0.8 to 1.2% per annum to reach 4.4 billion tonnes production by 2050 [7]. Fig.…”

Peat soil have been categorized as a problematic organic soil, because they have a high settlement rate when placed any structure on it. Therefore, the peat soil must first be stabilized using cement before it can be used. However, massive use of cement can lead to environmental pollution. Therefore, this study intends to use sugar cane bagasse ash as a substitute for cement in peat soil stabilization. The mix ratio of 5% to 20% was used to find the optimal mix ratio. Various tests were carried out on samples such as basic properties tests, Unconfined Compressive Strength (UCS) and Scanning Electron Microscope (SEM). After all the tests, the 5% replacement SCBA mix ratio gave the highest unconfined compressive strength if compared to the other mixtures ratio. Therefore, it is selected as the optimum mix ratio. The soil strength achieved by the SCBA 5% replacement ratio was found to be higher than cement stabilization alone due to the presence of secondary pozzolan reactions. The microstructure result from the SEM test had shown that the 5% replacement SCBA mix ratio filled in the hollow left by the peat soil. Hence, able to improve its soil structure and thus increasing its strength.

“…The results indicate the capability of SCBA as to partially replace the cement quantity in peat stabilization. It was found the SCBA percentages could extent up to 20% of cement replacement on Japan peat [17][18][19][20][21][22]. This paper presents an effect of SCBA that used as a cement replacement material on Pontian peat in Johor, Malaysia.…”

Malaysia covers about 2.6 million hectares of tropical peat deposits as shown in Fig. 1, where the accumulation and formation are favorable compared to the other tropics [1]. In term of country land area, Malaysia was ranked 10th in the world with 8% [2]. Among these land, 6,300 hectares are found in Muar, Batu Pahat and Pontian in West Johor. Peat in the district of Pontian, have been developed to agricultural for oil palm, pineapple and other food crops [3]. Geotechnically, peat are classified as highly organic soil that having more than 75 % of organic content which represent a problematic and poor quality of soil due to limited compressibility index [4]. Peat classification is important as they are weaker than inorganic soil that subsequently lead to instability and long term settlement when subjected to load [5]. Sugarcane industries contribute to 1.9 billion tons of by-products where one metric ton of sugarcane creates 280kg bagasse [6]. The utilization of sugarcane bagasse that were mainly utilized as to fuel sugar mill leave the bagasse ash as Abstract: Malaysia are covered approximately 2.6 million hectare of peat and facing serious geotechnical problems to develop infrastructure on peatland area. This study is to observe the basic geotechnical properties, strength and compressibility behavior of Pontian peat that stabilized by cement (OPC) and sugarcane bagasse ash (SCBA). The whole laboratory test standards and regulation that had been used in this study was adopted from American Society for Testing and Materials (ASTM) and British standards (BS). In order to understand an improvement of peat stabilization, unconfined compressive strength (UCS) and 1D-Oedometer consolidation test were conducted on untreated and stabilized peat. The results show that Pontian peat can be considered as hemic peat with average acidic. It was observed that the treated peat with 5% of SCBA (PCB5) has the highest UCS of 190 kPa and was discovered to be equivalent to PC specimen. There was a noteworthy decrease of void ratio, e for optimum PCB and PC mixtures as compared to untreated peat. The value of Cc and Cα was quite low at small effective stresses, however it improved after beyond preconsolidation pressure, σ'c. Compared to untreated Pontian peat which contributed the ratio of Cα/Cc about 0.056, stabilized peat for PC and PCB5 gave better ratio with 0.0316 and 0.0273 respectively. Results shows that the treated peat Cα/Cc ratios were drop dramatically from untreated peat which is representing the stabilized mixture can efficiently reduce the secondary compression.

“…Among the popular additives used in recent years for peat stabilization is cement. However, the use of cement is not economically viable due to large amount of cement required to cover a wide area of peat land [6]. To reduce the cost of peat stabilization, many studies were conducted using non-valuable local additives such as quarry dust.…”

Peat soil is one of the soil types available in Malaysia, which has a high compressibility and low shear strength. Thus, peat is considered inappropriate to support a construction site in its natural state. Among the methods suitable for the stabilization of peat soil is using a cement. However, the quantity of cement required in peat stabilization is quite large and made this method not too environmentally friendly due to carbon dioxide, CO2 emission from the cement production. Therefore, in this study, quarry dusts are used to partially substitute to ordinary Portland cement in peat soil stabilization. Quarry dusts were expected to potentially act as a pozzolan (containing cementitious properties to replace cement). Laboratory testing to determine the physical, chemical and mechanical properties were carried out to investigate the strength, acidity and the microstructure of the treated and untreated peat soil. For mechanical properties, Unconfined Compressive Strength test (UCS), was conducted to determine the peat soil strength., Chemical and microstructure (Scanning Electron Microscope (SEM) and Energy Dispersive X-Ray (EDX)) tests were carried out to assess the mechanism of strength gain in the stabilized peat soil. The results obtained show that by partially replacing the cement with 5% quarry dust, the soil strength increases from 47 to 684 kN/m2, which suitable for low loading construction such as car park area and outdoor sport court. The microstructural results also show PC and PCQ5 increases the calcium, Ca and decreases the carbon dioxide, which has an effect on increasing strength and decreasing the soil acidity.
