Flexural Strength of Concrete - Applications and Problems
Flexural strength is one measure of the tensile strength of concrete. It is a measure of an un-reinforced concrete beam or slab to resist failure in bending. It is measured by loading 6 x 6 inch (150 x 150-mm) concrete beams with a span length at least three times the depth. The flexural strength is expressed as Modulus of Rupture (MR) in psi (MPa) and is determined
To Perform Marshall Stability Test (ASTM D6927)
Marshal test is extensively used in routine test programs for the paving jobs. The stability of the mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 600 °C. The flow is measured as the deformation in units of 0.25 mm between no load and maximum load carried by the specimen during stability test (flow value may also be
Procedure for Concrete Sample Preparation
Concrete is placed in the molds using a trowel in three layers of approximately equal depth and is remixed in the mixing pan with a shovel to prevent segregation during the molding of specimens. The trowel is moved around the top edge of the mold as the concrete is discharged in order to ensure a symmetrical distribution of the concrete and to minimizeTo Determine The Metacentric Height Of a Ship Model
The intersection of the lines passing through the original center of buoyancy and center of gravity of the body and the vertical line through the new center of buoyancy.What are Survey Stations and How to Select a Survey Station
Survey Stations is a point of importance at the beginning and end of chain line. There are two types of survey stations: ... These are the end of survey line i.e. which connects boundaries. Line joining Main Stations is called Main Survey Line or Chain Line.To Measure COD of WasteWater using Open Reflux Method
KMn04 was used as oxidizing agent for many time pb with KMno4 was that different value of COD obtained due to strength change of KMno4. BOD value obtained greater than COD with KMno4 means KMno4 was not oxidizing all the substances.1/2 How to Download and Install Genuine P6 Software?

Deterioration of Concrete and Remedial Measures
Calcium silicates can be used to fill the pores and decrease the permeability. This can be done by treating calcium hydroxide with diluted sodium silicate (also known as Water-Glass). Pores can also be filled by treating Calcium Hydroxide with Magnesium Fluosilicate followed by the formation of Colloidal Silicofluoric Gel to withstand acid attack. Allowing the
California Bearing Ratio Test Procedure and Test Report
It is the ratio of force per unit area required to penetrate a soil mass with standard circular piston at the rate of 1.25 mm/min. to that required for the corresponding penetration of a standard material. The California Bearing Ratio Test (CBR Test) is a penetration test developed by
How to Remove Stains from Concrete
It is always better to remove the contaminant and clean the concrete surface as soon as possible because if it penetrates into the concrete, the removal of stains may be more difficult. To reduce the risk of contaminants penetrating into the concrete and make stain removal easier, a suitable sealer can be applied to the concrete surface when new or after cleaning.How to Add Activities in Project P3?
