For compression test, Total 36 cube specimens of size 150 x 150 x 150 mm were cast for M45 grade of concrete. The moulds were filled with different proportions of cement, glass powder. Vibration was given to the moulds using table vibrator. The top surface of the specimen was leveled and finished.
Solutions for safe transport and handling of field specimens are also available. Concrete Sample Molds include various types such as cylinder, beam, or cube molds used for compressive strength testing. Cylinder …
China Clay is a aggregate, the surrounding rock (such as a granite deposit) that is excavated to acquire the desired material (china clay) is the secondary aggregate. Recycled aggregate. Recycled aggregates come from reprocessing inorganic or mineral material that have previously been used in construction. Examples of recycled …
An 80mm down recycled crushed aggregate to the Highways Agency specification for capping, 6F5. 6F5 is used to cap off the subgrade or bare subsoil to be used as a base to construct roads and hardstanding areas on top of, it can also be used as a piling mat for a piling rig. The pure concrete version of this product is a higher quality alternative to the …
Aggregate Abrasion Value (AAV) – this is an estimate of the surface wear of road surfacing aggregate and is an indicator test for abrasion resistance. Aggregate particles (10-14mm) are mounted in resin mould and abraded using a specially designed machine. The percentage loss of the test specimen is the AAV.

Sampling for Crushing Test of Aggregate. For the Aggregate crushing value test, an aggregate sample passing through a 12.5 mm IS sieve and retained on a 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature. To fill the cylindrical measure mold about 6.5 kg of a sample of aggregate is sufficient.
The diameter of the cylinder cast must be at least 3 times the nominal maximum size of the coarse aggregate employed in the concrete manufacture. The apparatus required is mentioned below: ... cast iron or any mold made of non-absorbent material. Even under severe conditions, the moulds used must retain its original shape and dimensions. The ...

Bitumen, coarse aggregate, crush sand and fillers are the major constituents of the bituminous pavement. Recycled glass in the form of crushed culets or granules was used as an alternative for the fine aggregate. Glass possessing properties of high durability and skidding resistance, ... These moulds were tested for its stability and flow value ...
Cylinders must have a length-to-diameter ratio of 2:1 and a diameter three times the coarse aggregate's maximum nominal size. Concrete mixes with larger aggregate sizes must be wet-sieved to remove material coarser than 2in (50mm). The smaller size and lighter weight of 4x8in cylinders make them a popular choice when test methods and project ...
Concrete mix, that has little to no aggregate, will allow for a smoother pour and more defined cast. Whereas, a concrete mix with aggregate will be stronger and more durable for weight bearing castings like tiles and pavers. Our goal is to help direct you to products that perform exceptionally well when making concrete based crafts and …
• Porosity- Porous aggregate may crush when compressive loads are applied before the failure in the mortar bond between the aggregates can occur. The compressive strength will lower if less dense or porous aggregates are used. ... It is therefore a must to compact concrete in the cube moulds as well as in the structure properly until such ...
Concrete cube tests are performed to determine the compressive strength and other overall characteristics of concrete. In this destructive testing method, concrete cubes are crushed in a compression testing machine. The cubes used in this test have a dimension of 150 x 150 x 150 mm provided the largest aggregate does not exceed 20 mm.
A single sized 40-80mm crushed concrete and tarmac without fines, this material is ideal when the ground that you wish to use as a roadway or hardstanding is particularly boggy, muddy or wet. As there are no fines the material is more able to bind with the underlying subsoils to make a hard base.
