1 Concrete What is Concrete? Concrete is perhaps the most versatile of all constrction materials. In its freshly mixed condition it can be pored, pmped and molded into a variety of forms and shapes, while in its hardened state it can be sed for many constrction prposes. The qality of concrete is crcial if strctres are to be safe and serve the prpose for which they were designed. Or concrete testing eqipment gives yo the ability to measre and prove the qality of each batch of material, so that yo can ensre the correct application of the key raw materials. Cement 34 Fresh and Hardened Concrete Testing 35 Non-Destrctive Testing of Hardened Concrete 36 Compression Machines 37 Compression Machine Accessories Cement is a man-made material and can be spplied in many forms, with different cements having specific and often varied properties, sch as rapid hardening, slphate resistance and low heat. The precise cement content for different batches of concrete will normally be specificed at the time of manfactre; typically, concrete has a cement content of abot 250 kg/m 3. Sections 38 and 39 describe test eqipment specifically designed for the testing of cement. Aggregate By far the greatest proportion by volme of concrete is made p of aggregate. This can be natrally occrring, sch as river gravels, or crshed rock from qarrying operations; other materials can also be sbstitted for aggregate inclding colliery waste and recycled concrete. Normally, coarse and fine aggregates are sed in the proportions of approximately 70:30. Section 42 describes test eqipment sitable for the testing of concrete aggregates. Water Water reacts with cement and allows the necessary hydration and hardening process to proceed. The qality of water is not generally critical providing it is clean and free from imprities and high silt content. The qantity of water added does, however, have a major effect on the qality and strength of the concrete. Test eqipment designed to determine the effect of water on fresh concrete is described in Section For 24/7 online ordering, payment & order tracking go to

2 34 Concrete - Fresh and Hardened Concrete Testing Sampling, Consistency and Workability The correct sampling and mixing of fresh concrete is important if test reslts are to be reliable. Most of the eqipment necessary for efficient sampling and mixing is standard laboratory eqipment detailed in the Laboratory Eqipment section of this cataloge. To ensre that concrete achieves its maximm possible strength and yet retains its ease of placing on site, it is essential that the design of the concrete mix, in relation to the water-cement ratio and workability, is closely controlled. Slmp Test EN ; ASTM C143; AASHTO T119 Accessory Scoop see EL K-slmp Tester Developed to determine the workability of fresh concrete and the degree of concrete compaction placed in formwork. The apparats can be sed for in-place measrements of concrete in test molds and forms and may be correlated to the standard slmp test. It is simple, economical to se and redces testing time. No special calibration is reqired. EL K-slmp Tester. Weight 450 g. Test is appropriate for concrete mixes of medim and high workability The test is carried ot by filling the slmp cone with freshly mixed concrete, which is tamped with a steel rod in three layers.

3 34 Concrete - Fresh and Hardened Concrete Testing Vebe Time BS EN Test appropriate for concrete mixes of low and very low workability This method is a mechanised variation of the slmp test and incldes a determination of the workability of concrete. It is based on the principle of sbjecting the concrete to vibration after removal of the slmp cone. The assembly is monted pon a small vibrating table operating at a fixed amplitde and freqency. The time to complete the reqired vibration gives an indication of the concrete workability. Special Note: The consistometer mst be operated from an electrical spply of 50 Hz in order to comply with the fixed test freqency specified.

27 37 Concrete - Flexral and Transverse Machines and Accessories Flexral and Transverse Testing Machines and Accessories The flexral and transverse strength of concrete is of interest to engineers for many reasons. Movement of strctres which may be indced by e.g. temperatre changes, grond vibrations, cyclic loading of road pavements and many other external inflences, will set p internal stresses within a concrete member. There is no clearly defined relationship between compressive and flexral strength. Generally it can be assmed for most prposes that flexral strength of normal concrete is abot 10% of the compressive strength achieved in the same concrete. Modern concrete technology tilises a wide range of materials sch as glass or steel fibres to improve the flexral strength of the concrete. These modified concretes often reqire the se of special tests and eqipment. Lower loads are sed to test concrete in flexre; however, the shape and size of test specimens is sch that larger and often heavy specimens can be difficlt to handle. ELE has designed the range of machines offered to provide for ease of specimen positioning and sbseqent testing. The range of flexral test eqipment offered provides a wide variety of choice and test methods inclding low strength compression tests sing optional ball seating assemblies. 85 For 24/7 online ordering, payment & order tracking go to
