Malasida The fresh concrete is poured into a cone as used for the EN bw test. Allow gs filled cone to stand for not more than 30 s; during this time remove any spilled concrete from the baseplate. It is desirable, especially the case of new constituents or new concrete compositions, to test the consistence of fresh SCC before casting in place. The surface shall not be readily attacked by cement paste or be liable to rusting. We have no document history for this standard.

Malasida The fresh concrete is poured into a cone as used for the EN bw test. Allow gs filled cone to stand for not more than 30 s; during this time remove any spilled concrete from the baseplate. It is desirable, especially the case of new constituents or new concrete compositions, to test the consistence of fresh SCC before casting in place. The surface shall not be readily attacked by cement paste or be liable to rusting.

We have no document history for this standard. All lines to be a maximum of 2,0 mm wide and 1,0 mm deep. Then measure the diameter of the flow spread at right angles to d to the nearest 10 mm and record as d to the nearest 10 mm. Proceed em Checkout Continue Shopping. For undated references, the latest sn of the referenced document including any amendments applies. If the difference 1 2 between d and d is greater than 50 mm another sample shall be taken and the procedure repeated.

Slump-test 3 Principle The slump-flow and t time is used to assess the flowability and the flow rate of self-compacting concrete in the absence of obstructions. ENTesting fresh concrete, consists of the following be As the voice of the U. Check the top surface for horizontality using the spirit level. Please first log in with a verified email before subscribing to alerts. The plate shall have a flat, smooth surface.

Since SCC has to give satisfactory in-situ properties perfect filling of the mould and embedment of the reinforcement, homogeneity and full compaction without vibration, the proper methods for testing the fresh SCC are very important.

Place the cone centrally within the mm circle on the baseplate and hold in position by standing on the foot pieces or use the collarensuring that no concrete can leak from under the cone.

The result is an indication of the filling ability of self-compacting concrete. These should address three key properties: When the cone is withdrawn upwards the time from commencing upward movement of the cone to when the concrete has flowed to a diameter of mm is measured; this is the t time. Prevent skin contact with wet cement or concrete by wearing suitable protective clothing.

Take precautions to avoid dry cement entering the eyes, mouth and nose whilst mixing concrete. Organizations of all sizes and across all sectors choose standards to help Copyright them achieve their goals. The largest diameter of the ej spread of the concrete and the diameter of the spread at right angles to it are then measured and the mean is the slump-flow. Clean the table and the cone and dampen immediately prior to testing, but keep free from excess moisture.

If the t time has been requested, start the stop watch immediately the cone ceases to be in contact with the baseplate and record the time taken to the nearest 0,1 s for the concrete to first touch the mm circle After the flow of concrete has stabilized without disturbing the baseplate or concrete, measure the largest diameter of the flow spread and record as d1 to the nearest 10 mm.
