Q: Does exposure to petroleum-based lubricating oils and transmission fluids cause concrete floors to disintegrate? A.: Pure mineral oils such as gasoline, fuel oils, lubricating oils, and petroleum distillates reportedly don't attack mature concrete (Refs. 1 and 2). However, a book published in 1950 (Ref. 3) says that lubricating oils are often improved by adding fatty …
Concrete itself cures more slowly at low temperatures and therefore needs the benefit of the curing medium longer, thus cancelling out at least part of the benefit of slower …
during concrete curing; and (3) wide-scale adoption of this technology within the concrete industry. The potential for emissions reductions and CO 2 storage have already been demonstrated. The production of CSC, as a replacement for Portland cement (PC), can reduce CO 2 emissions at a cement plant by decreasing energy and limestone consumption.
Allow new concrete to cure for at least 30 days before applying any clear coat. For previously painted floors, assess the condition of the paint. If the paint is old and flaking, it is advisable to strip it off completely and start with a fresh surface. ... Temperature and humidity significantly impact drying times. Avoid painting when the ...
Removing Diesel Fuel Stains from Concrete: A Step-by-Step Guide Initial Steps: Absorb the Spill: If the diesel spill is recent, immediately cover it with an absorbent material like litter or sawdust.These materials will soak up excess fuel, preventing it …
Concrete is perfectly happy to cure underwater where it never dries out. So the effect of any kind of curing membrane, whether it is plastic sheets, liquid, or even diesel, is to …
Aeolian sand is distributed worldwide, exhibiting poor grading, low cohesion, and loose structure. Infrastructure construction in desert areas sometimes requires stabilization of the sand, with cement as the primary curing agent. This study first employed orthogonal experiments to evaluate critical factors, e.g., curing time, cement dosage, and water dosage, affecting the …
A company supplying concrete and cement goods in Kuantan announced a price increase of RM12 for the delivery of each cubic metre of blended cement within a radius of 30km. Chia said transport entrepreuners under his association could not give specific details on future price increases. "It varies based on the company and location," he added.
Concrete Curing pH Level Impacts for Minimization of Harm to Aquatic Species. 2. Background Construction and maintenance actions regularly require state Department of Transportation(s) (DOT) to cast concrete structures below the ordinary high water lines of streams. Recently-cast concrete is known to increase the pH level of water it contacts ...
Understanding the impact of adverse weather on concrete curing is essential for determining when you can safely start framing. Many believe that concrete cures uniformly regardless of weather conditions, but this is a misconception. Adverse weather can significantly influence the curing process, affecting the timing for subsequent construction ...

Minimizing environmental impact Preserving the natural environment while delivering our business promise. ... in Japan, is a result of a merger between Idemitsu and Showa Shell Sekiyu. Its sales in Japan are primarily gasoline, diesel oil, kerosene and automotive lubricants. Idemitsu Kosan owns and operates more than 6,400 retail service ...
To minimize the adverse impact of steam curing on concrete performance and identify the main factors affecting the diffusion coefficient of concrete, this section is based on the grey system theory [28] and the grey correlation analysis method is applied [29]. Particularly, the correlation between the diffusion coefficient of chloride ions and ...
It is necessary to find the impact of petroleum products (kerosene, petrol and diesel) on the strength as well as other properties of the concrete.

The water uptake depends on the cement immersion time in a biological fluid and it is studied through sample mass variation analysis. The weight loss is determined after immersion (function of the time) and drying. Starch botanical variety and enzyme presence do not impact curing parameters and water uptake but strongly influence degradability.
