T...WISDOT allows slag and fly ash in the concrete. The carbon left on the fly ash destroys the air entraining ability of the concrete making it more susceptible to breaking under conditions of temperature changed. Wisconsin experiences temperature differences of about 140 degrees. This is why our roads seldom last years and they should last decades!<br /><br /> http://www.flyash.info/2009/068-jolicoeur2009.pdf<br /><br /><br /><br /><br />http://wisconsindot.gov/rdwy/stndspec/ss-07-15.pdf#ss715<br />The contractor may use class C fly ash or grade 100 or 120 slag as a partial replacement for cement. For<br />binary mixes use up to 30% fly ash or slag, except for slip-formed work the contractor may use up to 50%<br />slag. For ternary mixes use up to 30% fly ash plus slag in combination. Replacement values are in<br />percent by weight of the total cementitious material in the mix.Anonymousnoreply@blogger.com
