Grouted Brick Prism

Volume Concrete Delivers Grout for Grouted Brick Prisms

Masons like the Grout from Volume Concrete thanks to the freshness (mixed on-site), and the ability to adjust the slump on-the-fly, and vary the sack amount for the cement component.

Admixtures on board include Viscosity Modifiers for increasing the flowability and increasing the consolidation around rebar and other components that may lead to blockage.

The Grout from Volume Concrete is easily pumpable through a small line pump thanks to lack of aggregates and the increased amount of fine sands.

This particular Grout is a High-Strength Flowable Fill with p.s.i. strengths exceeding the 2000psi requirement usually required in the local market.

Here are some recent test results for 28 day strength.  PC2500 GROUT

Call Dispatch to order Grout and don’t forget the Pump!

Up to 9 Sacks per Cubic Yard depending on job-site requirements.

Testing Exceeding: ASTM C1314 & C1552

Cold Weather Concrete Success Tips using Accelerators and Water Reducing Admixtures

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.

Hot Water Every Load

The time is here and the temperatures are dropping. The HOT WATER is in every delivery and already included in the price, no additional charges.

Volume Concrete LLC., uses hot fresh potable clean water for all loads and deliveries beginning in October through April.

Hot water acts as a catalyst to help kickstart the chemical reaction that occurs when hydrating cement. This will help the concrete achieve an early set during colder temperatures.

Why use Air Entrainment in freshly poured concrete?

The key to a high quality concrete in addition to high quality cement is the admixtures. Today’s chemicals for concrete and the construction industry are suited for a variety of applications. This particular chemical is Air Entrainment from BASF.

In the process of making concrete the agitation causes a certain amount of air bubbles to be generated within the freshly mixed concrete. This amount of naturally occurring air bubbles is roughly 2% on average. The necessity to have air bubbles in concrete is due to the frost and freeze cycles we generate in Oregon.

The more air bubbles (up to a certain point), helps the concrete withstand the severity of the frost/freeze. The cold weather will cause the moisture that can be trapped within the cellular structure of concrete to freeze causing the surface to “pop off” or spalling. More air bubbles from the Air Entrainment Admix = less moisture to freeze.

Spalling concrete is bad, causes more problems down the road and thus can be avoided by adding more Air to the concrete during the mixing process. Volume Concrete LLC., uses the finest quality chemicals sourced from BASF. All the admixtures we use are compatible with themselves.

Thanks to the Crew at Roadmaster, our mixer trucks have robust measuring and calculating capabilities for correct dosage of all admixtures we carry.
