Engineering properties and sustainability indices of seawater-mixed concretes produced with supplementary cementitious materials such as fly ash, slag, and metakaolin

This file consists of data from the published article titled, 'Seawater-mixed concretes containing supplementary cementitoius materials: Compressive strength, e-modulus, electrical resistivity, and life cycle assessment' in the journal Archives of civil and mechanical engineering. 

The excel file consists of 7 sheets and each sheet represents the data included from Fig 2 to Fig 8.  

Sheet 1 named as Compressive strength (Fig 2) consists of mean compressive strength values at ages 1, 7, 28, and 91 days in 20 concrete produced with and without seawater mixing and also its experimental standard deviation (of 4 replicas). 

Sheet 2 titled as Fig 3 (% change in strength) contains the % change in compressive strength (from 100 mm cube specimens) between fresh and seawater-mixed concretes. 

Sheet 3 consists of elastic modulus for 20 concrete mixes (100 mm dia and 200 mm height cylinders)  included in this study.  Both mean and standard deviation values (of 3 replicas) are listed. 

Sheet 4 named as Fig 5 (Resistivity) includes both surface and bulk resistivity measurements carried out in concrete cylinders (100 mm dia and 200 mm height) using Wenner resistivity 4 probe device.  Measurements were conducted on 3 different cylinders and each cylinder was measured at 4 locations (0, 90, 180, and 270 degrees).

Sheet 5 named as Fig 6 (Carbonation). This consists of mean and standard deviation values of carbonation depth measured in 100 mm diameter and 50 mm thick disc specimens.  Accelerated carbonation test was carried out in a chamber with CO2 concentration controlled at 5%, relative humidity (65%), and temperature 25 deg C. 

Sheet 6 named as Fig 7 (GWP) contains the calculated values of global warming potential for all the 20 concrete mixes considered in the study 

Sheet 7 named as Fig 8 (WDP) contains the calculated values of water depletion potential of 20 concretes made with fresh and seawater mixing.
