Abstract. This report presents the results of an experimental program dealing with the rheology of fresh concrete. The three main goals were: 1) Obtain rheological data on concretes produced with various mixture compositions; 2) Establish models to link mixture composition with rheological properties; 3) Develop a new simple field test that ...

Flexural Strength is the ability of a beam or slab to resist failure in bending. It is measured by loading un-reinforced 6×6 inch concrete beams with a span three times the depth (usually 18 in.). The flexural strength is expressed as "Modulus of Rupture" (MR) in psi. Flexural MR is about 12 to 20 percent of compressive strength.

The test involves placing fresh concrete in layers in a slump cone, tamping each layer with a rod, then removing the cone and measuring the distance the concrete falls. A true slump of 1-2 inches indicates low workability, 2-4 inches is medium workability, and over 4 inches is high workability. ... This PPT describes all the different test on ...

Test methods to determine workability of Self Compacting Concrete are: 1. Slump flow test. The slump flow test is used assess the horizontal free flow of self compacting concrete in the absence of obstructions. The test method is based on the test method for determining the slump. 2. V Funnel Test.

Procedure to Test Temperature of Fresh Concrete (ASTM C1064) The concrete mix is sampled as per ASTM C172 and mixed thoroughly.

The slump test (ASTM C 143) m e a s u res concrete consistency, or the ability of fresh concrete to flow. Slump is commonly mistaken as a m e a s u r e of workability—the ease in which fresh concrete can be placed, consolidated, and finished. Figure 2. Remove the slump mold uniformly; don't use a twisting or jerking motion. Note lines on mold

Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, …

Presentation Transcript. Fresh Concrete Materials of Construction Dr. TALEB M. AL-ROUSAN. Introduction • Long term properties of hardened concrete (strength, volume, stability, and durability) are seriously affected by its degree of compaction. • Consistency or workability of fresh concrete should be such that …

Fresh concrete has several important properties from mixing until it hardens in its final location. Its workability, defined as the effort to manipulate it with minimum segregation, depends on factors like water-cement ratio, aggregate properties, time, temperature, and cement characteristics. Workability is measured using tests like slump …

Concrete is a composite material made by binding aggregates with a cement paste. It comes in various types depending on the binding material (cement or lime) and purpose (plain, reinforced, pre-stressed). Good concrete has strength, durability, density, water tightness, workability and resistance to wear and tear.
