Flexural Testing Machine Flexural Testing Machine (As per IS: 516, BS: 1881, ASTM C78) Introduction Although generally not such an important property of concrete than compressive strength, tensile strength values are often important to know when the concrete used free of reinforcement and may be subjected to some tensile force. The test method essentially involves …

Vee Bee Consistometer Vee Bee Consistometer Introduction The Veebe consistometer measures the remolding ability of concrete under vibration. The test results reflect the amount of energy required to remold a quantity of concrete under given vibration conditions. The Veebe consistometer is applicable to concrete with slumps less than 2 inches. The apparatus, consists of a …

Concrete Thermometer Concrete Thermometer Introduction Temperature of concrete at the time of placement is important to control and to avoid many possible difficulties. In hot climates, it is important to measure the temperature of the fresh concrete to ensure it is not too hot, which could cause flash setting and rapidly reducing workability. Measurements are …
Concrete Test Hammer Concrete Test Hammer Introduction Often, existing concrete structures will need to be examined and tested to ensure the concrete remains of adequate strength and durability. Rebound hammer surveys can be conducted to provide a rough estimate of concrete strength, where it is not possible to determine this by more accurate means such …
Concrete Permeability Apparatus Concrete Permeability Apparatus Introduction A concrete structure is considered to be of adequate durability if it performs in accordance with its intended level of functionality and serviceability over an expected or predicted life cycle. Concrete durability depends largely on the ease (or difficulty) with which fluids (water, carbon dioxide, oxygen) in the …
Tile Abrasion Tester Tile Abrasion Tester Relevant Standard : IS : 1237, IS : 1706. Introduction The tile sample is pressed under a specified load against a grinding path strewn evenly with an abrasive powder revolving at the rate of 30 + 1 r.p.m. At the end of 100 revolutions of the disc the second …
Slump Test Apparatus Slump Test Apparatus Introduction The oldest, most widely used test for determining workability. This test is used to determine the workability of fresh concrete, which would normally be undertaken at the point of delivery to ensure the concrete, is of adequate consistency for placement. The test is applicable to concrete of medium …
