PL ADVICE THAT HOW TO CALCULATE THE SEISMIC FORCE FOR A CEMENT SILO.. HORIZONTAL FORCE AT BASE

This is best done by a qualified engineer in the load region.

But the short answer is with an algorithmic analysis that calculates the combined forces on the structure in a compound. Today, more emphasis is being given to the foundation below a structure as part of the analysis.

small batch plant

I will be starting a home building project with multiple slabs and long drive’s. using about 1500yds of concret and with a possibilty of using another 1500yds within a year. I was considering buying a used smalll concrtete plant and buying the materials whole sale and making my own concrete on site. Do you think it would be finacially benifefical to do this? I have done major projects like this in the past but have not made my own concrete.

The return on investment in a complete state-of-the-art plant that will match the product your ready mix supplier provides you is probably in the range of 25,000 to 50,000 cubic yards per year.

Your own mixer trucks and drivers + your own boom pump with operator would be worth investigating first--then the plant.

BATCH PLANT INFO

TRYING TO FIND OUT THE COST OF A BATCH PLANT, BOTHE PORTABLE AND FIXED.

Portable "plants" can cost as little as $100,000.00 or as much as $1,000,000.00 and fixed plants can run from $250,000.00 to $3,000,000.00.

It's a bit like houses or cars--there is a wide range. Tell me a little more about what you plan to do, what market you are looking at, and perhaps we can narrow it down a bit!

Concrete Pumping System

Robert, I’m looking for a machine that can pump concrete from one area to another, in hard to get at areas. If such a product, I looking for one that is hand held, or possibly something using a hose. I’m a foundation contractor some jobs require installing steal beams that I reinforce by pouring contrete in the hollow areas of the beam facing the foundation wall. If you know of a machine or if you can recommend something I would appreciate it. I look forward to your answer with great interest. And, thanks Robert for you time. JC.

JC,

There are a number of good small pumps for jobs like the one you describe.

Try the Concrete Products Buyers Guide as a reference. Brands like Pft, Putzmeister, HANY and ChemGrout come to mind, but there are others as well.
