Rutte (SCP and Urban Mine) from the Megapool Amsterdam, SmartCrusher BV has put the finishing touches to the SlimBrekers 2 / SmartCrushers 2 (SC2) (or SmartLiberator as it is called at Rutte). The SC2 is intended to free all fractions from traditional precrushed concrete rubble, and that at approximately 40 tons per hour.
• Proper design and construction are absolutely necessary if the pavement is to perform. • Must be uniform throughout pavement's life. • Poor subgrade/subbase preparation can not be overcome with thickness. • Any concrete pavement, built of any thickness, will have problems on a poorly designed and constructed subgrade or subbase.

design EAL when the thickness of crushedstone base was varied from 3 to 6 inches. Therefore, the design thickness of the portland cement concrete slab is relatively insensitive to changes in thickness of the crushedstone base. Resulting thickness design curves are presented for a
The concrete minimum compressive strength will be specified by the client/designer in a specific format. An example of this is given below: C40/50. The 40 is the compressive requirement of 40 N/mm² of a crushed 100m concrete core and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete .
crusher's discharge opening, as the production continues through an online coarse size analysis of the crushed product (digital image analyses). Dance, A. 2001) • More attention is being paid to the impact on crushing circuit design caused by variations in ore characteristics, size distribution, moisture content, ore grade and climatic
Abstract In this paper describe the design and calculation of concrete mixer for weight 350 kg approximately. A concrete mixer machine is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. Concrete is an important component required for construction of houses and roads.

The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

Concrete pipe design is different from plastic or steel pipe design because concrete pipes behave in a different manner to flexible pipes. Concrete or other rigid pipes will deflect very little during loading which prevents any lateral pressures being developed in the surrounding soils leading to no lateral support.

The crushed aggregate sample which is finer than mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the "ten percent fines value" should be determined ...
