The winter months can make concrete a challenge. Anything below 32 degrees Fahrenheit is not recommended especially considering if the ground is frozen solid.
Concrete is in a plastic state (wet) when initially delivered and mixed. This wet product will have a tendency to freeze just like water. Once a concrete mix has frozen, it is worthless.
To avoid the costly mistake of frozen concrete a few steps must be taken.
Always use hot water and an admixture containing an accelerator and a water reducer (WR). An accelerator alone is often sufficient until temperatures become exceedingly cold. By using an additional admixture WR, the probability of the concrete turning into frozen crystals is less.
Another important aspect to cold weather concreting is the reduction of exposure to the elements. Cold weather insulating blankets are a necessity when it is critical to maintain the temperature within the plastic concrete. Once the hot water and admixtures have been mixed, the concrete has thus started it’s chemical reaction. It is very important to not re-temp the concrete by adding more water or chemicals.
Volume Concrete LLC., uses admixtures that meet ASTM C494 type C accelerating and type E WR, requirements.
What is a Detectable Warning Surface? What kind of concrete is needed for Tactile replacement in Oregon (see below)?
The primary purpose of a cross-walk at an intersection for the the safety of the pedestrian. Yet, many accidents occur in the cross-walk involving pedestrians, cyclists and automobiles.
Too address the major issue involving cross-walk accidents, an innovative solution is taking hold across our communities by using a concrete tactile.
The concrete tactile is a cast-in-place product offered by many companies that is essentially a Detectable Warning Surface used to ALERT individuals of the dangers. Often times these tactile surfaces are placed at intersections, and cross-walks.
ADA Pads are another term used to describe the Detectable Warning Surface.
What Is a Curb Ramp? A curb ramp is a short ramp cutting through a curb or built up to it. If designed and constructed to be accessible, a curb ramp provides an accessible route that people with disabilities can use to safely transition from a roadway to a curbed sidewalk and vice versa. – via ADA Tool Kit
What kind of Concrete is needed for Tactile Replacement in Oregon and the Portland Metro? Volume Concrete LLC., delivers a 4,000psi mix that adheres to the local building codes and requirements. This specific mix design is dialed specifically for the Detectable Warning Surface and ADA Tactile, allowing for an easier install without compromising strength or workability.
Note: Each City, County and State have specific requirements regarding the concrete mix design, and it is important to do due diligence in researching those community-specific requirements.
The ADA Standards require that curb ramps include features called “detectable warnings.” Detectable warnings consist of a series of small domes that contrast in color with the surrounding sidewalk or street. They must be integrated into the walking surface, and there are specific measurements for the size and spacing of the domes. – via ADA Tool Kit
A list of the most common, relevant and noteworthy questions about the volume.
How many cubic feet are in a cubic yard of concrete? Answer: 27 cubic feet equals 1 cubic yard.
How many square feet can I get out of 1 cubic yard of concrete when the depth of the slab is 3.5 inches thick? Answer: 80 – 100 square feet for every 1 Cubic Yard of Concrete, as long as the thickness is no more than a standard nominal 2×4 (actual dimension being 3.5″ tall).
Water to Cement Ratio? Volume Concrete LLC., adheres strongly (no pun) to the industry standard of optimal hydration at .35 that is for every one (1) pound of cement we aim to only add .35 pounds of clean pure water.
How many pounds of cement are in a sack of cement? In North America, the domestic system, we honor the 94 lbs./per sack requirement.
Do Not wait for Bleed Water, Start Finishing Immediately!
Have Lots of People and Experienced Finishers
Have a lot of wheel barrows, emphasis placed!!!
This product begins wet, but very quickly loses slump.
Have an area for clean up with running water and scrub brushes for the tools.
Mixer Trucks will require an area for cleanup immediately following the pour, we cary water on-board.
Typical temperatures are 40°F – 85°F, colder temperatures require hot water and need protection from the elements. Hot temperature pours are avoided during peak temperatures, and require burlap and water to protect the product once poured.
When using for repairs, application surface must be clean, sound and free from any materials that may inhibit bond, such as oil, asphalt, curing compound, acid, dirt and loose debris. Mechanically abrade surface and remove all unsound material. Saturate the surface before the HESC hits the ground. Avoid standing water or puddles, this will affect the strength of the final product.
