M30 grade of concrete is considered while performing tests and analyzing, it shows that 10% replacement of cement by palm oil ash (POFA) gave high strength compared to conventional concrete. All the results generated are compared against control mix which gave an impression of improvement in (mechanical, strength) parameters of concrete …
Experimental investigation, based on early data, suggests that palm oil fuel ash can suitably be used as a strong and durable cement replacement material in concrete. Pozzolanic materials, either natural or artificial, have been used for long in concrete construction. Being artificial pozzolana, fly ash and later rice husk.
This research studies the effects of W/B ratios and palm oil fuel ash (POFA) on compressive strength, water permeability, and chloride resistance of concrete. POFA was ground until the particles retained on sieve number 325 were less than 5% by weight. POFA was used to partially replace OPC at rates of 15, 25, and 35% by …

The general strength of OPS concrete samples produced high strength concrete with compressive strength reaching up to 52.2N/mm 2 for 28 days. 50% is sufficient for …
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]. Hence cement/ water ratio of 0.5 was used in this research with mixing ration of 1:2:4. Cast iron mould of 150 x 150 x

The influence of a crude oil spill on concrete weakening and swift have remained a gray topic in the literature. According to the findings, ... Evaluation of the consequence of crude oil pollution on concrete materials strength. The experimental investigation is conducted on concrete that is both new and hardened samples to …
Hydrocarbons can adversely affect the hydration of fresh concrete if intermixed i.e. they retard concrete strength gain. Results from analysis where a concentration of hydrocarbons was introduced into the mix water indicated the potential loss of 25% in strength. When hydrocarbons are in contact with hardened concrete, generally, there …
Influence of Oil Products on Strength and Durability of High Strength Latex Modified Concrete Coated by Epoxy
During conducted tests, the influence of mineral oil on the long-term strength of normal-strength and high-strength concretes has been documented [15, [20] [21][22]. After 280 days, the ...
