LONG-TERM TESTING Large UK consulting firm needs geological laboratory for monthly geotechnical soil tests including: sulphate reducing bacteria/reduction/oxidation potential/pH (corrosivity test), electrical resistivity, XRD test, resonant column, cyclic shear strength under combined average and cyclic loads for triaxial and direct simple shear (DSS) stress paths, creep data to define loss of strength under sustained load, remoulded soil consolidation characteristic (compressibility and permeability), reconsolidated remoulded soil strength characteristics, and thixotropy.
Test Request 17-00724
UK geology laboratory needed for clay testing for suitability for end uses as clay bricks, tiles, ceramics etc. Scope of testing to include:
An initial gradient firing on each borehole material (10 samples) to determine the firing temperature / colour related to each clay test piece after first milling to a suitable particle size range for clay brick manufacture.
Stage 2 work scope
The following tests will be carried out on the sample as received borehole material (10 samples):
· Particle size distribution - to be determined using both the sedigraph and dry sieving method, to cover the full size range of particles from millimetres to microns. The results would be collated to provide a full particle size distribution.
· XRF Analysis (with Loss on Ignition) - to be carried out to determine the bulk inorganic composition of the following 19 elemental oxides: SiO2, TiO2, CaO, MgO, K2O, Na2O, P2O5, Cr2O3, Mn3O4, ZrO2, HfO2, Al2O3, Fe2, PbO, ZnO, BaO, SrO, SnO2, CuO and SO3 (SO3 reported as remaining after loss on ignition fusion and is not for an accurate SO3 figure).
· Soluble Sulphate using Ion Chromatography on water soluble extract from each borehole.
· Total Carbon & Total Sulphur using the Leco total combustion technique to determine the percentage total sulphur and total carbon of each borehole material.
Stage 3 work scope
The following processing to take place on each borehole material to prepare fired specimens (5 samples selected after stage 2):
· Dried and Fired Shrinkages on five (5) appropriate prepared clay samples: to be tested for each borehole material to determine both the dried shrinkage from green state to after drying at 110 C, and shrinkage from being dried at 110 C to fully fired specimens. The firing temperature will be confirmed for each borehole material after the initial gradient firing.
· Water Absorption - on five (5) appropriate prepared clay samples: to be tested for each fired borehole material
· Summary Report - Summarizing all data with conclusions on the best materials for brick making, referencing typical brick properties.
· Fired samples retained to use as reference samples
