Metoda rapida de evaluare a rezistentei standard a cimenturilor

Investigations carried out in the testing laboratory at CEPROCIM SA have led to devising an experimental model designed to quantify the thermal effect released during early hydration of cement up to reaching the maximum temperature in relation to the strength of the respective cement. The paper presents the results obtained using this experimental model within the testing laboratory in Fieni Cement plant, CARPATCEMENT HOLDING SA for cement CEM I from current cement production. Application of the correspondence relation y = f(x), where y is the 28-day compressive strength and x is the early heat of hydration (Q hM ), has led to a rapid assessment of the cement standard strength with a precision of ±2.5 MPa.
