INFLUENCE OF OIL PALM SHELL ON WORKABILITY AND COMPRESSIVE STRENGTH OF HIGH STRENGTH CONCRETE. 1, A mix proportion for LWC is quite different from the mix proportion of high strength concrete or normal strength concrete. For the LWC, which is to be produced from using OPS as aggregate requires an average cement/water ratio [8]. Cited by: 5


The used cooking oil obtains the optimum contribution to the concrete mix proportion of containing used cooking oil of 1.50% from the cement content. The result of used cooking oil from experimental program of slump value and compressive strength proved that used cooking oil have positive effects on replacement of commercially available superplasticizer.


concrete specimens with high strength and corroded reinforcements gave higher degradation of bond strength. According to the previous studies, it is demonstrated that the influence of oil pollution for steel bars on concrete strength has not been studied concisely so far. Thus, further investigations in this direction are considered essential.


5. Used engine oil maintained the concrete compressive strength whereas the chemical air-entraining admix-ture caused a loss of approximately 50% in compres-sive strength at all ages. When a water cement ratio of 0.59 was used for the oil mixes, the following conclusions were made after assessing and comparing the test results of these oil

described. Comparing the influence of various oil products on the compressive strength of concrete leads to the conclusion that there are large differ­ l'nccs in effects. From vascline oil with almost no in­ fluence to some mineral oils with the serious influ­ ence, even to 30 or 50% loss of initial values. Con­


This paper studies the influence of oil products )gas oil and gasoline misname benzene) on strength and durability of high strength latex modified concrete. Three percentage (5, 7.5 and 10% by weight of cement) of styrene butadiene rubber latex (SBR) were used in this work to produce Latex Modified High Strength Concrete (LM-HSC).

Received on 12 June 2008 . Abstract . The costal areas of Nigeria are polluted with oil due to oil spillage and pipeline vandalism. The


Consequently, the present study focused on the impact of diesel oil and bitumen on compressive strength of concrete. Marine sands were contaminated in the order of …


Used engine oil with a water cement ratio of 0.59 maintained the flexural strength, splitting tensile strength, and modulus of elasticity of the control mix with water cement ratio of 0.62. 5 The 28- and 90-day concrete compressive strength of the used engine oil mix with a water cement ratio of 0.59 improved by almost 20% as compared with the control mix with a …

The adverse effect to the concrete strength upon using too much of palm oil fuel ash as partial cement replacement has been reported by other researchers [20, 21]. Figure 3 . Effect of POFA content on workability of OPS Figure 4 .


The Effects of Fire on Concrete. As we discussed in our last blog, there are often multiple types of damage to the building materials.An understanding of the mechanical and physical properties of the building materials and the effects that heat has on those properties are important aspects of the damage assessment.


In this study, the effects of a new type of non-metallic fiber (polypropylene twisted bundle (PPTB)) on the slump and mechanical properties of oil palm shell (OPS) concrete have been investigated. The results showed that increasing the volume fraction of PPTB fibers, it slightly decreases the workability and density of the concrete. It has found that the …


Cement which is highly responsible for hydration enthalpy and also the cost of cement which makes it uneconomical. The only way to deal with this kind of challenge is by introducing different products to replace certain amount of cement. An environmental friendly waste product produced from agricultural industries known as POFA (Palm-oil-fuel-ash) can be replaced with certain …

Effect of Oil Contamination on Properties of Concrete Mineral oil in water, that have no animal or vegetable oil content have no adverse effect on the concrete properties. The mineral oil content to a percentage of 2% is said to increase the strength of the concrete. But for more than 8% mineral oil, the strength is reduced. Read More

used engine oil increased the slump and percentage of entrained air of the fresh concrete mix, and did not adversely affect the strength properties of hardened concrete. KEY …


The reduction in strength can be related to the varying percentages of crude oil contamination in the concrete, which may lead to loss of water content/moisture and preventing absorption of water by the concrete cube when cured in water. This occurrence has effect on the hydration of cement in the concrete cubes.
