LS600 PUMP — GENERAL INFORMATION
more readily pumpable mix with superior water retaining
qualities. However, if delays are likely to occur, extra care
must be exercised due to the faster setting time over regular
cement.
The Mayco LS600 models will pump a wide variety of
concrete pump mixes. But, there are guidelines that must
be followed. Use this information in conjunction with the
Operation
section of this manual.
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
28 days.
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:
1.
Pea rock (1/2" minus) pump with mixes being as low
as 30% rock and 70% sand. (See page 44, for
comments on cleaning the pump.)
2.
Shortening pea rock when used with an air compressor
and nozzle. (See back pages for recommended setup.)
3.
“Mud Jacking”, high pressure grouting.
