Aggregates INTRODUCTION Mineral aggregates are used in all fields of the construction industry to produce bituminous mixtures, concrete, mortars to be used in structures, fill materials, railway ballast, etc. For this reason we have given particular attention to all testing methods. The new EN standards have grouped all tests on aggregates in five main subjects: - Tests for general properties of aggregates - Tests for geometrical properties of aggregates - Tests for mechanical and physical properties of aggregates - Tests for thermal and weathering properties of aggregates - Tests for chemical properties of aggregate. In the majority of cases the new EN Standards correspond to some existing National Standards and, apart from a few exceptions there is almost no difference in the specifications of test apparatus.

y the time this catalogue has been printed a number of new European Standards concerning aggregates will have been published and the correspondent National Standards are automatically superseded. The new EN Standards for aggregates have been grouped in five main subjects: Standards - Tests for general properties of aggregates from EN 932-1 to EN 932-6 - Tests for geometrical properties of aggregates from EN 933-1 to EN 933-10 - Tests for mechanical and physical properties of aggregates from EN 1097-1 to EN 1097-10 - Tests for thermal and weathering properties of aggregates from EN 1367-1 to EN 1367-5 - Tests for chemical properties of aggregates from EN 1744-1 to EN 1744-3 In the majority of cases the new EN Standards correspond to some existing National Standards and, apart from a few exceptions there is almost no difference in the specifications of test apparatus. In order to allow clients the choice to update, if necessary, their laboratory equipment, we list below all the new EN Standards with corresponding National Standard. Considering that in many countries outside Europe the National Standards such as BS and NF will still be adopted, we continue to supply the relative apparatus.

General description and specifications The machine consists of a rolled steel drum having an inside diameter of 711 mm and internal length 508 mm. The drum is rotated by a speed reducer driven by an electric motor at a speed of between 31 and 33 r.p.m. The machine is equipped with an automatic counter, which can be preset to the required number of revolutions of the drum. The unit is supplied without the abrasive charge, which has to be ordered separately depending on the standard in use. Conforming to the CE directive, the machine should be housed in a soundproof and protection cabinet.

and other components are located in the top of the cabinet for easy inspection and maintenance. Thermostatic unit The cooling group, CFC free, is overspecified for the maximum reliability. It is designed to condition the air circulating in the cabinet. The cooling group consists of a compressor mounted on antivibration supports with internal thermal protection, copper tube condensers with aluminium fins, motor fans directly connected to the shaft and complete with thermal protection. The cooling circuit is entirely made of copper and is completed with de-water/ receiver filter, spy glass to verify the passage of freon, high pressure manostat and inlet connectors. The evaporator has the same characteristics of the condenser. The de-humidification is obtained by a smooth tube with cyclic thaw. The heating element consists of a stainless steel finned tube with a limit thermostat. The re-cycling fans are connected directly to the low thermal emissions motors.

Chloride, carbonate content / Potential reactivity / Organic impurities

 chloride content of fine aggregates - bs812 M 48-D0543 Quantab chloride titrator, type 1175 (711175), range 0.005% to 0.1% Na Cl. Bottle of 40 strips M 48-D0543/A Quantab chloride titrator, type 1176 (711176), range 0.05% to 1% Na Cl. Bottle of 40 strips General description and specifications A simple and quick method to determine the chloride content of fine aggregates. The silver dichromate strip will react with any chloride in the solution and the calibrated column will indicate the proportional concentration of chloride. Bottle containing 40 strips and calibration chart.

 carbonate content of aggregates M 48-D0570 Gasometer Dietrich-Früling General description and specifications Used for the determination of CaCO3 especially in limestone and lime marl. It consists of a glass container in which the reaction between the calcium carbonate contained in the products and a solution of hydrochloric acid takes place. The gas given off is collected and measured with a suitable device connected with the container. Being measured the volume of gas (CO2) given off it can be related with the quantity of CaCO3 contained in the sample.

Used in the test method for the chemical determination of potential reactivity of aggregates with alkalies in Portland cement concrete. Manufactured from corrosion-resistant metal and fitted with an airtight cover. Capacity: 59 cm3 approx.

General description

General description and specifications Used to crush aggregates, core samples, and similar materials when a reduction in sample size is necessary. The crusher has a jaw opening of 100x60 mm and can produce from 100 to 400 kg of material per hour. The movement of the jaws can be regulated from 5 to 15 mm. The laboratory crusher is supplyed with a separate control panel Motor: 736 W B Dimensions: 650x550x500 mm A Weight approx.: 90 kg

The hammer mill executes the grinding operation using the principle of the combination of three efforts: impact, shear and rebound. Once entered into the grinding chamber through the hopper, the material reaches the wished fineness and trough the filtering hoses arrives to the collector. General specifications - Grinding chamber dia. 180 mm - 3,4 interchangeable fixed hammers - Output grain size: “rise” type (4÷5 mm) - Possibility of installing screens with various opening size according to the wished grain size - Max. hardness of the material to grind: 6÷7 Mohs - Maximum capacity: 50 kg/h - 380 V, 50 Hz, 3 ph., 500 W

The machine is supplied complete with: - screens of 1, 2 and 3 mm opening - safety microswitch - electric control board - filtering hose - powder collector B Dimensions: 500x600x900 mm
