Laboratory tests Malaga and Huelva | Geosand

Geosand has its own laboratory, accredited and registered in the Register of Laboratories for Quality Control of Construction of the Ministry of Public Works and Transport of the Junta de Andalucia with the number LE107-MA08. It has implemented a quality system UNE-EN ISO 17025.

Laboratory tests contribute data very interesting in relation to the geotechnical studies. Its main objective is to inform about the terrain-tough physical responses on a number of requests and efforts.

Depending on the information that we seek, we will either laboratory test. Among the most common are:

- Identification test

Particle size, humidity and Atterberg limits. This type of testing is essential to characterize a particular field and its type (gravel, clay or sand). This information allows focusing the geotechnical study the most appropriate way in each case.

- Simple compression breakbreak

This test is simple, fast and economical. It allows the specialist to determine the compressive strength of soil subjected to an axial load. It is especially useful when purely cohesive materials (clays) are handled.

- Direct shear test

With this test you get information on the cohesion and angle of internal friction of soil, that is on components of cutting effort it. To do a piece of land exerting tangential forces breaks.

- Lambe trial

It allows you to identify those areas tending to change volume due to changes in humidity content. It is a quick and effective way of assessing the expansiveness or retraction of the soil.

- Free swelling and swelling pressure in oedometer

As in the previous case, these essays also provide information about the terrain expansiveness. With the free swell test soil humidification occurs to measure the swelling sample, with the swelling pressure test one proceeds in the same way except that stresses or loads are applied to prevent swelling.

- Test dimensional consolidation in oedometer

This test can be defined predictable seats in the materials forming the ground. This information is important to avoid deficiencies in the structure as such materials are relatively soft in comparison to the most widely used building materials, and tend to deform under load further.

- Soluble sulfates

This test belongs to chemical tests and determines the aggressiveness of the concrete soil by analyzing the sulphate content of the soil in question.

- Triaxial test

Cohesion and friction angle of the soil: triaxial test with highly relevant information is obtained. It is crucial to know in detail since these two parameters to define the soil bearing capacity.
