requirement that the cement-mortar thickness be determined while the mortar was wet. Asphaltic Seal-coat The use of a seal-coat was first introduced in the 1953 edition of ANSI/AWWA C104/ A21.4. Research conducted by the Cast Iron Pipe Research Association from 1940 to 1952 showed that a thin asphaltic paint coating, applied to the freshly placed cement-mortar lining, would greatly minimize ...
The first and main criteria controlling the thickness of slabs is deflection. Generally, slabs can safely carry their own weight and the gravity loads imposed on them, without much trouble, and reinforcement is mostly nominal and for crack prevention.

2007-03-09· I am trying to find out how to determine the req'd concrete thickness under a column that has a vertical load of 28.2 kips (O/T moment = 37.1 kip-ft) I would like to put the column on a 6" thk. pedestal with anchor bolts to secure the steel column (10" Y beam).
Concrete Countertop Thickness and Weight Learn about size limitations for concrete countertops This 36-foot long bar countertop was created without seams and to appear extra thick.
1. Calculate the super-imposed loads (dead weight of storage tank and liquid in the same) on the concrete slabs; 2. Calculate self weight of the concrete slabs; 3.
The thickness of concrete depends on its application. You'll need to consider the soil or sub-grade conditions in the location you're laying the concrete. Before deciding on a thickness for concrete, consider these 6 questions.
The formula for calculating the weight of concrete is: Length (in feet) x Width (in feet) x Thickness (in inches) /12 x 150 = weight (in pounds). For example, the weight of a 7-foot-high door, 3 feet wide and 12 inches thick would be: 7 x 3 x 12/12 x 150 = 3,150 lbs.
What is the correct thickness of stucco? What is the installed weight of portland cement plaster? What is the proper spacing for contraction/expansion joints in portland cement plaster/stucco applications?, Why use building paper? ...
The application determines the thickness of the concrete. Moreover, you will also be required to consider the sub-grade or soil condition of the area where the concrete will be laid. The sidewalks that are made from concrete are usually 4" thick. If a sidewalk is used by service vehicles or crosses a driveway, it should be 8" thick.
Structural concrete work is planned to bear loads, or hold weight, but transfer the weight to the soil base beneath the structure. The thickness of concrete is an important factor in load-bearing strength, but to conserve resources and avoid over-building, other factors are also taken into consideration.
Specification for Concrete Weight Coating 3 of 10 1.0 SCOPE This specification shall govern the materials, application, inspection, repairs, handling and other
The weight change usually is made by using a different coarse aggregate. For example, aggregates such as expanded shale are used to produce concrete for elevated decks and other applications where weight is a concern. This type of lightweight mixture often is in the 90- to 110-pounds-per-cubic-foot range. At the other end of the spectrum, heavyweight aggregates, such as hematite, can be used ...

2010-02-09· RE: Concrete thickness versus load jike (Structural) 9 Feb 10 10:39 When you say 3500#, is this the lift capacity of the truck, the empty weight of the truck or the loaded weight or the front axle weight?
2005-03-11· I am tryng to find out how thick the cement would have to be to hold say a 10,000 pound machine. How long would it have to cure for at 70 degree's before placing the machine on it?
Hire a licensed engineer to test the sub soil conditions at the foundation site to ensure it has the load bearing capacity for the foundation concrete weight as well as the weight of the machine tool and its workholding/tooling capacities.
2014-01-06· That seems a little thin. Having a contractor chop a hole in the floor and pour two feet on concrete isn't that expensive. The machine will probably be fine if …
The buoyancy of concrete pipe depends upon the weight of the pipe, the weight of the volume of water displaced by the pipe, the weight of the liquid load carried by the pipe and the weight of the backfill. As a conservative practice in analysis, the line should be considered empty so the weight of any future liquid load is then an additional safety factor. Pipe Weights The average density of ...
The specification for the floor of a maintenance building called for a 6-inch slab thickness and concrete with a design compressive strength of 3000 psi. The actual average cylinder strength for the floor concrete was 3630 psi. Four months after the floor

2015-06-05· *Concrete can be produced to different strengths, and the thickness determines weight capability. Contact a ready-mix concrete company for information on various 'mixes' and strengths. Contact a ready-mix concrete company for information on various 'mixes' and strengths.
The concrete thickness gauge by PCTE is a simple and handy device used for generating and receiving sound waves to measure the thickness and find the defects in concrete…
2003-06-13· We are moving into a new building that has a 4" concrete slab. We want to put a 26,000 lb machine in there. The machine sits on 4 legs, equally loaded, so it runs 6,500 lb each.
Concrete containing lightweight aggregates and carbonate aggregates retain most of their compressive strength up to about 1200 o F. Lightweight concrete has insulating properties, and transmits heat at a slower rate than normal weight concrete with the same thickness, and
A common bag of concrete, for example, may have a compression strength of 4,000 psi, based on a thickness of 2 inches after it has set for 28 days. Other concrete may have a …
