Definitions

  • the given invention is referred to building materials production and can be used to define the activity of Portland cements and their variations as well as strength of any heavy concretes manufactured on the basis of this cement.
  • Table 1 gives activity parameters for purely clinker Portland cements received by formula 1 at different temperatures
  • the technical result of the invention is in reducing time for defining cement activity, higher accuracy of the received results for water and cement amount in concrete mixture.
  • the given method enables within a short period of time to define with maximum accuracy cement activity, cement and water amount in concrete mixture.
  • the method is performed in the following way: one takes Portland cement of any type, produced by simultaneous grinding clinker and gypsum (together with mineral additives or without them), prepares water-cement mixture of definite concentration by stirring it for 30-60 seconds, then he lowers the conductivity meter and measures S.C. and temperature in a special device constructed for defining cement activity and concrete strength and equipped with a special program where other characteristics of cement and concrete mixture are introduced, resulting in defining cement activity, cement and water amount in concrete mixture and predicted concrete strength.
  • Formula (2) gives the value of cement activity in bending.
  • Strength value in compression where the member -91 ⁇ / ⁇ is absent in formula (2), is calculated as follows:
  • coefficient C one can take concrete mixture produced on the basis of that cement lot for which C is determined by previously known specific consumption.
  • Total water amount in one cubic meter of concrete mixture is calculated according to the formula:
