***General Introduction***
This dataset contains data on concrete mechanical properties (slump, compressive strength, percentage water absorption, percentage permeability, normal consistency and time of set), physiochemical properties of potable water and tropical landfill leachate. Experiments were conducted at the University of the West Indies, St. Augustine for an Master of Science (MS) Thesis research project (June 2018): doi: 10.4121/uuid: 540a1bba-a5a3-4069-ab07-83d11984768b.  It is being made public as supplementary data for publications and the MS thesis of Samantha Jagmohan as well as for other researchers to access and use this data in their own work. The data in the dataset were collected in the Civil Structural Laboratory of the University of the West Indies – Faculty of Civil and Environmental Engineering, Trinidad Cement Limited (TCL), Caribbean Analytical Sciences Limited (CASL) and the Water and Sewerage Authority (WASA) between January 2018 and April 2018, 
Purpose of the test campaign
The purpose of these experiments was to investigate the structural integrity of concrete cubes that were modified using treated- and untreated tropical landfill leachate with specific emphasis on mechanical and microstructural properties. 
Test equipment 	
Slump was measured on the fresh mortar following American Society of Testing and Materials, ASTM C143/C143M-15a.Compressive strength of three representative standard-cured test specimens were tested at age breaks of 3d, 7d, 14d, 21d and 28d.The cubes were tested on their sides between the steel plates of the ELE Compression Testing Machine at pacing rate of 150kN/minute according to BS 1881: Part 116, BSI London Protocol. The Maximum Failure Load at which the cube failed was indicated on the meter and was noted in KiloNewtons, kN. The Compressive strength (MegaPascals, MPa units) was calculated using maximum failure load divided by cross-sectional area of cubes. Percentage water absorption and percentage permeability was done using oven-drying method according to ASTM C642-97. Normal consistency and time of set was conducted at the Trinidad Cement Limited (TCL) Chemistry laboratory using the Vicat Method as outlined in ASTM C187-98. The potable water parameters were tested at the chemistry laboratory at the Water and Sewerage Authority of Trinidad and Tobago (WASA) while the tropical landfill leachate samples, both treated and untreated were tested at the Caribbean Analytical Sciences Limited (CASL), Trinidad office.
***Description of the data in this data set
*** The data included in this data set has been organized per specific sheets. In order of data compilation, sheet 1 contains the compressive strength, sheet 2 water absorption and percentage permeability, sheet 3 slump and time of set, sheet 4 the potable water physical and chemical analysis and the final sheet with the tropical landfill leachate physical, chemical and biochemical analysis.
