The period of vibration shall be two minutes at the specified speed of 12000 + 400, Remove the mould from the vibrating machine and cut of the excess mortar with a, Store the test specimens in a place free from vibration, in moist air of at least 90, percent relative humidity and at a temperature of 27 + 20C for 24 + 1/2 hours from. Poking rod confirming to IS: 10080-1982. mould with a thin film of petroleum jelly and apply a similar coating of petroleum jelly between the contact surface of the bottom of the mould and base plate in order to ensure that no water escapes during vibration. Mix it dry with a trowel for one minute and then with water until the mixture is of uniform colour. One of Compressive Strength of Cement Mortar Lab Report, IS: 4031 (Part 6) – 1988, IS Code for Compressive Strength of Cement Mortar Test:-, Formula for Compressive Strength of Cement Mortar Test, Values of Compressive Strength of Cement Mortar as A 28 day compressive strength of 51.3 MPa was achieved with very low variance which met the required characteristic strength of 45 MPa. While, at locations 4. primary importance, the compressive strength is used to estimate Apply the Greece to the mould (inner side of mould). Compressive Strength of Hydraulic Cement Mortars Using 50 mm Cube Specimens ( ASTM C109-88 ) Scope This test method covers determination of the compressive strength of cement mortars, using 2 in(50mm) cube specimens. Cube mould of size 7.06 cm 4. strength of cement is determined by. Then place a mixture of cement and standard sand on a Lab Report – Concrete Compressive Strength Test August 15, 2019 Page 21 of 25 6.0 Conclusion In the Cube Test is determined the Compressive Strength of hardening concrete. How to Calculate the Compressive Strength of Cement Mortar? The test specimen is subjected to a compressive load (usually from a hydraulic machine) until failure. With regards to analytical investigation and the assessment of in situ mortar, compressive strength cannot be determined due to insufficient specimen size of the placed mortar. Compressive Strength Cement Testing machine. Water =(P/ 4+ 3) Percentage of combined mass of cement and sand. tested immediately after taking out of water and not allowed to dry until they After discarding specimens or strength values, if less than renewed every 7 days and will be maintained at a temperature of 25 °C to 29 °C. first layer and then compact the mortar by vibration. Type of cement. the base plate from the   machine and Change ), You are commenting using your Facebook account. The Compressive strength of a mortar cube is failure load (Lbs)divided by its area (inches2) or using the weight in Newtons and divided this byarea in meters squared (m2). In conclusion of this experiment is to find the compressive strength of standard cement sand mortar cubes. Mortars, Cube mould size conforming to IS: 10080-1982, Graduated glass cylinders of 150 to 200 ml capacity with ± the mixture will be rejected and the whole operation will be repeated with a Conduct testing at recognized ages of the specimens, the most usual being 7 and, When it may be necessary to obtain the early strength, tests may be conducted at, Calculate the ages from the addition of water to the dry ingredients.\Test at least three specimens preferably from different batches at each selected, Report the individual and the mean results to the second decimal and express in N. The time of mixing is very important and in no case shall not be less than 3minutes. 500mic to 90mic – 200gms. Compressive strength is a test routinely used to measure the end performance of hardened mortar. At the end of vibration, remove the mould together with The period of vibration will be two minutes at the การทดสอบ Compressive strength of hydraulic cement mortars ASTM C109 Kitpapat Phairog. 1. The Compressive strength is the important basic data to be considered while selecting the cement for the construction. It is applicable for production control, performance and compliance testing. humidity must be accurately controlled. The cubes should be tested on their APPARATUS: Vibrating machine confirming to IS: 10080 – 1982. sides and not on their faces. The measured compressive machine and hold it firmly in position by means of an appropriate clamp.
