Workability of Concrete - Definition and Types - Civil Gyan

Fig 1. Slump Test for finding Workability: Workability is an important property of concrete and linked with compaction as well as the strength of the concrete. The desired workability for different grades of concrete is not the same. Greater workability is preferred for a thin inaccessible section or heavily reinforced section rather than for mass concreting. Hence, we cannot set standard

Non-Destructive Testing of Concrete - We are Civil Engineers

Core Extraction for Compressive Strength Test; Penetration Test Method . The Windsor probe is usually considered to be the best way of testing penetration. The equipment consists of a gun or powder is driven, hardened alloy probes, loaded cartridges, a depth gauge to measure probe penetration, and other related equipment. A .25-inch diameter probe. (6.5 mm) and length 3.125 in. (8.0 cm), is

Figure 2: Compressive strength vs. cube no at 7, 14 and 28 days Patil et al. [10]. Patil et al. [10] deduced the comparative study of the effect of curing on strength of concrete using DT and NDT methods. 27 cubes of M25 grade were casted and allowed to be cured for 7, 14 and 28 days and rebound hammer test and compressive strength test was

Influence of High Water Pressure on Static and Dynamic

In this paper, an experimental study was conducted on the influence of water pressure on concrete strength. Specimens were put in a self-designed device, applying 0-4 MPa water pressure on concrete, and then taken out for both static and dynamic compressive tests. Results showed that high water pressure caused inevitable damage to concrete, leading to 13.4% reduction in strength under

Compressive Strength Test Of Concrete Cubes - Engineering

Compressive strength as a concrete property depends on several factors related to the quality of used materials, mix design and quality control during concrete production. Depending on the applied code, the test sample may be cylinder [15 cm x 30 cm is common] or cube [15 cm x 15cm x 15 cm is the most common].

Compressive Strength Test on Concrete Core - Calculation

Calculation of Compressive Strength of Concrete Core. Calculate the compressive test of the specimen using the computed cross sectional area based on average diameter of the specimen. If the L/D ratio is 1.75 or less, correct the result obtained by multiplying with correction factors as given below: L/D Ratio.
