(betegnelse "Igepal DM"). Begge de første to overflateaktive midler er anioniske og 'det tredje overf lateaktive mdddel er ikke-ionis.k....» (designation "Igepal DM"). Both the first two surfactants are anionic and the third surfactant is non-ionic.
Som ikke-ionisk klassifiseres også poly(etylenoksyd)-harpiksene som anvendes ifølge foreliggende oppfinnelse. (. The poly(ethylene oxide) resins used according to the present invention are also classified as non-ionic. (.
Polyetylenoksydharpiksene utgjøres av .homopolymere,r med den generelle formel' HO-CH2CH2-(0-CH2CH2)-0H. Polymerisa-sjonsgraden n varierer 'fra ca. 2000 til 100.000, hvorved tilsva-rende molekylvekter varierer fra lOOVOOO til 5•000.000. Ifølge foreliggende oppfinnelse anvendes fortrinnsvis en harpiks med en molekylvekt på ca. 400.000. ' Slike harpikser.'er oppløselige i vann og er blitt benyttet som ét pumpe-hjelpemiddel for betong. Disse harpikser oppviser ekstraordinær fortyknings-evne. Ettersom harpiksene er viskoelastiske har de evne til å absorbere mekanisk energi, fra turbulente hvirvler og å frigjøre slik lagret energi langsomt eller i en forsinket virknings- 1 rekkefølge. Denne effekt som betegnes slippreduksjon 'medfører som netto resultat at væsketransporten eller væskens bevegelse gjennom ledninger forbedres. Holdbarheten.av blandingen er ikke spesielt kritisk. Fagmannen kan lett .bestemme når denne blanding har blitt ensartet. The polyethylene oxide resins consist of homopolymers with the general formula HO-CH2CH2-(0-CH2CH2)-OH. The degree of polymerization n varies from approx. 2,000 to 100,000, whereby corresponding molecular weights vary from 1000,000 to 5,000,000. According to the present invention, a resin with a molecular weight of approx. 400,000. Such resins are soluble in water and have been used as a pumping aid for concrete. These resins exhibit extraordinary thickening ability. As the resins are viscoelastic, they have the ability to absorb mechanical energy from turbulent eddies and to release such stored energy slowly or in a delayed action sequence. This effect, which is termed slip reduction, has the net result that the liquid transport or the movement of the liquid through lines is improved. The shelf life of the mixture is not particularly critical. The person skilled in the art can easily determine when this mixture has become uniform.

Et annet fenomen som har tendens til å inntreffe, spesielt ved varmt og tørt vær, er at etter hverandre fylte seksjoner ikke bindes godt sammen slik at man kan få en fugeløs struktur, selv om bare en kort tidsperiode kan ha forløpt mellom påfyllingen av de to seksjonene. Evnen til å bibeholde egen-skapen av en seksjon so,m forenes med en deretter påfylt seksjon av betong, betegnes som oppvisning av en "våt kant". Tilsatsen ■ ifølge foreliggende oppfinnelse muliggjør at betongsammensetnin-gen i hvilken, den anvendes oppviser en funksjonsdyktig våt kant i lengre tidsperiode. ' Another phenomenon that tends to occur, especially in hot and dry weather, is that successive filled sections do not bond well together so that a jointless structure can be obtained, even though only a short period of time may have elapsed between the filling of the two the sections. The ability to retain the property of a section which is joined with a subsequently filled section of concrete is referred to as exhibiting a "wet edge". The additive ■ according to the present invention enables the concrete composition in which it is used to exhibit a functional wet edge for a longer period of time. '
