REFERENCE SANDS FOLLOWING THE EQUIVALENT CONCRETE MORTAR (MBE) METHOD PROPERTIES OF MBE SANDS
This method makes it possible to design, from a concrete composition, a mortar – called equivalent mortar (MBE) – whose rheological properties (subsidence and spreading in the mini-cone) are correlated with those of concrete.
To make this mortar, SNL makes so-called reference sands.
Formulation
Bag weight
The weight of the bags can vary from 1 kg to 3 kg depending on the specific request. The grain size distribution is guaranteed to +/- 2 gr and the total weight defined by the customer is guaranteed to +/- 2 gr.

Sand ASTM C778 graded, 25 Kg, SNL, France
STANDARD SAND ASTM C778 Graded
Cement Testing – Standardized Sand Specifications
CHARACTERISTICS
Graded sand is composed of local natural siliceous sands (silica content 99%) with a water content of less than 0.1%. The constituent grains of these sands are uncrushed, rounded in shape. This sand is used to test cements according to ASTM C 109.
The sand is packaged in 25 kg bags.
Deliveries are made individually and on pallets of 2 to 40 bags, protected by reinforced cardboard.
CONTROLS
The granularity of graded sand is fixed by standard ASTM C 778 and determined according to standard EN 933-1. The average production control is:
Tamis maille carree (mm) | Passants cumules (%) | |
Courbe moyenne | C778 graded | |
1,180 | 100,000 | 100,000 |
0,600 | 97,000 | 96 to 100 |
0,425 | 69,000 | 65 to 75 |
0,300 | 26,000 | 20 to 30 |
0,150 | 1,000 | 0 to 4 |
This sand has been certified in accordance with the ASTM C778 20-30 standard by the TERRACON laboratory (Texas). These checks are carried out by the SNL laboratory. They are the subject of a certificate per delivery.

#Analyses Sieves Test Sand
Details
This test sand was designed for internal monitoring of typical mashes of sieves (2,0 – 1,0 – 0,5 – 0,25 – 0,125 mm). The grain size distribution was developed in context of a round robin test of 147 national and international laboratories. The forerunner organization of the dakks (German national accreditation body), the DAP (Deutsches Akkreditierungssystem Prüfwesen GmbH, Berlin), published due to the round robin test a technical document, which recommended to use the Analyses Sieves Test Sand for regular calibration. Thus, the Analyses Sieves Test Sand is suitable for simple operation tests beside the obligated visual and intermediate tests.
Specification

Production
There is no natural sand available, which fulfills the grain size distributions demands of EN 196-1. Thus, the CEN Standard sand is an artificial product consisting of several different sand type fractions. The sand type fractions are industrial produced by sieving. The different sand fractions are blended in defined portions. The selection of the raw sands, the sieving of the fractions and the following blending are the most difficult processes, which have to be continuously performed as precise as possible. Due to that CEN Standard Sand producer are pledged to control and document the grain size distribution of the product at least once a day. Furthermore, monthly 28 days compressive strength tests under consideration of an actual and an one year old CEN Standard Sand sample have to be done and compared in a clearly defined procedure. Further comparison tests have to be carried out by an external inspection body.
