CVEN 3400 – Structural Testing Laboratory Lab 7: Lightweight Concrete Mix Design Laboratory Assignment Procedure 1) Follow the lightweight concrete mix design procedures from one of the online resources that I provide below: Read over the following 4 documents: http://www.fhwa.dot.gov/everydaycounts/technology/bridges/pbeswebinartraining/s4_m10.cfm U.S. Department of Transportation Federal Highway Administration (FHWA) Prefabricated Bridge Elements and Systems Lightweight Concrete Benefits for PBES Deployment by Reid W. Castrodale, PhD, PE, Carolina Stalite Company, Salisbury, NC http://www.norliteagg.com/structuralconcrete/mix_designs.asp Norlite Lightweight Aggregate: Mix Designs: Structural Concrete http://theconstructor.org/concrete/design-of-lightweight-aggregate-concrete/6734/ The Constructor: Design of Lightweight Aggregate Concrete http://www.schundler.com/mixdesigns.htm The Schundler Company Construction Guide: Lightweight Concrete Mix Designs How will you alter the procedures applied in the normal concrete mix design to account for the lightweight aggregate used in the lightweight concrete mix design? Review the following report: http://www.ltrc.lsu.edu/pdf/2006/old_reports/Report%20033.pdf Durability of Lightweight Concrete, Phase I -- Concrete Temperature Study, H.R. Rushing, 61-8C, August 1968 (Louisiana Transportation Research Center) 2) Obtain the manufacturer information (manufacturer, model number) for the scale. Record this information. 3) Obtain the manufacturer information (manufacturer, model number) for the concrete mixer. Record this information. 4) Record the material information for the materials used in the concrete mix. Lab Report 1) In a table, display the actual amount of material used and the theoretical (calculated) amount of material used. 2) What is the initial slump test value?
