Regional Differences

Concrete is made by mixing locally available rock and sand with cement and water. For this reason there are great differences in the pumpability of concrete from one region of the country to another.

It is impossible to define a specific mix for each region that the concrete pump be will working in. Therefore, the mixes listed in Appendix - Concrete Mix Information will provide a basic guideline for establishing the proper mix design for your area.

Use this information to specify your requirements to your local ready-mix batch plant, contractor and civil engineer. It may take minor adjustments to make a mix pumpable, so you should explain your needs.

The elements that have to be controlled and consistently maintained by the batch plant are:

1.The sizing and mix percentage of rocks, gap graded from the largest down through the smallest sizes.

2.Sand with a sieve analysis that has the proper percentage of fines, ASTM C33 spec.

3.Sufficient cement to produce the required design strength of the concrete and provide the lubricating binder to pump the concrete through the delivery system.

Use a minimum of:

„„500 lbs. of cement/cu yd for 2500 p.s.i. concrete after 28 days.

„„530 lbs. of cement/cu yd for 3000 p.s.i. concrete after 28 days.

„„600 lbs. of cement/cu yd for 4000 p.s.i. concrete after

28days.

4.Admixture pump-aid if necessary.

5.The proper amount of water to make a workable slump and plasticize the mix.

In addition, this Mayco Concrete Pump can be used to pump a large aggregate hard rock as follows:

„„Pea rock (1/2" minus) pump with mixes being as low as 30% rock and 70% sand. (reference maintenance for recommendations on cleaning the pump.)

„„Shortening pea rock when used with an air compressor and nozzle.

„„“Mud Jacking”, high pressure grouting.

Remixtures

Remixtures that are designed into the concrete mix by the redi-mix company or an architectural engineering company.This section lists common admixtures and a brief explanation of their functions:

1.Pozzolith 300 — Or the equivalent acts as a water retarder and a lubricant. On a lean mix, long pushes, stiff mixes, and vertical pushes, Pozzolith 300R helps pumpability.

2.MBVR — Air entraining, acts as a lubricant.

3.Calcium Chloride — Commonly referred to as C.C., is used as an accelerator. When pumping a load with calcium chloride, it is recommended that you wash out if the waiting time between delivery trucks becomes too long.

4.Super Plasticizers — Acts as an accelerator. The concrete will look very wet after the super plasticizer is added, but will begin to set up very fast. Wash out immediately if you do not have a truck waiting. Super plasticizers are used mainly on commercial jobs.

5.Red Label — Acts as a water retarder and an accelerator. Red label will be used mainly on commercial jobs.

6.Fly Ash — Is used to help increase the strength of the concrete and decrease the cement content per yard. This is one of the most common admixtures used.

NOTICE

All admixtures will be shown on the redi-mix concrete ticket. Before starting the pumping job, ask the driver of the redi-mix truck to see the concrete ticket and note the admixtures that exist and take the proper action.
