These solid blocks are commonly used for foundation of structures. EBF hollow blocks are produced in all standard sizes & shapes according to customer requirements in OPC & SRC construction, which are greater than or equal to 7.5N/mm2 in accordance with BS 6073Ĭoncrete Solid Masonry Blocks are produced according to BS6073, part 1. These hollow blocks are widely used for building infrastructure & require low maintenance. Our portfolio of products is manufactured at three locations in Al Mafraq and Al Ain.Ĭoncrete Hollow Building Blocks are produced according to BS 6073, part1. We are the Emirates’ Leading manufacturer of concrete blocks and meet international specification for technology, quality, services and the environment. Our state-of-the-art manufacturing facility is based on German Technology from “MASA” and “HESS”. Our large format architectural pavers are manufactured in Al Ain.Īt Emirates Block we provide a range of benefits and solutions to our customers through our extensive and diverse range of quality concert block. Our concrete blocks are produced at Emirates Blocks Factories in four facilities located in Abu Dhabi and Al Ain, with a total capacity of 235 thousand blocks/day, while our dry mortar facility is strategically located at Al Mafraq to serve both Abu Dhabi city and Al Ain. Our products have been showcased in prestigious projects throughout the Emirate of Abu Dhabi. Our dry mortar mixes complement our product range with more than 120 textures and colours to satisfy the most demanding architects. Nowadays, wireless maturity sensors are used to monitor the strength gain of these ditched cylinders (those that failed the compression test), to monitor the strength over time.Īll standard-cured cylinders are made and tested on 28 days for acceptance purposes and strength with age is determined through maturity sensors.Arkan’s portfolio of concrete products ranges from regular blocks used for construction of villas, buildings, and retaining walls to high end architectural pavers for landscaping with varied finishes of colours and shapes. If the sample still shows low strength, the mentioned causes must be studied and corrected. One way to avoid low-strength concrete breaks is to wait for the complete curing of the concrete and conduct the test on the next break day. Calculation Errorsīefore performing a compression test, the compression testing machine must be properly calibrated. The test specimen won’t break properly under the applied test load if the cured specimen is not prepared by grinding or capping its ends. If this is not corrected, the strength value of sample testing won’t be given by the real concrete structure. Improper Curing Conditionsįield-cured test specimens do not reflect the strength values of in-situ concrete samples. Improper handling and transportation of concrete test samples would result in cracking. The improper casting of concrete cylinders results in a test specimen that is not prepared for compression testing. This results in a compressive strength test value lower than expected. Preparing the wrong concrete mix results in delaying the concrete strength gain within the time that has been specified. The six key causes of low-strength concrete cylinder breaks are: 1. If the average of three consecutive tests is not equal to or exceeds the specified strength.The individual compressive strength test of one or two cylinders is more than 500 psi below the specified strength, or.Low-Strength Results of Concrete Cylinder- ACI 318 & ACI 301Īs mentioned in ACI Building Code ACI 318 and the Standard Specifications for Structural Concrete ACI 301, a concrete mix proportioned to meet the requirements of the standards and under compression test has chances of low-strength results about once or twice in 100 tests due to normal variability.Īs per ACI and CSA, a cylinder break during a compression test is considered to be of low strength when: Low-Strength Results of Concrete Cylinder- ACI 318 & ACI 301.
