Description

40°С на 24 ч. Затем их вынимают из воды, удал ют избыток воды с поверхности и испытывают на прочность при по ГОСТ 310.4-76.40 ° C for 24 hours. Then they are removed from the water, excess water is removed from the surface and tested for strength with GOST 310.4-76.

Предел прочности при сжатии в сухом и насыщенном состо нии половинок образцов вычисл ют как среднее, из шести испытываемых половинок соответственно сухих и насыщенных образцов. На основании этих показателей вычисл ют коэффициенты разм гчени  как отношени  предела прочности образцов при сжатии в насыщенном водой состо нии (Рнас.) к пределу прочности образцов при сжатии, высушенных до посто нной массы (Рп.м.) РнасThe compressive strength in the dry and saturated condition of the halves of the samples is calculated as the average of six test halves, respectively, of dry and saturated samples. Based on these indicators, the softening coefficients are calculated as the ratio of the ultimate strength of the samples under compression in a water-saturated state (Rnas.) To the ultimate strength of the samples under compression, dried to constant weight (Ppm.) Rnas.

Сроки схватывани  теста определ ют по времени от начала затворени  композиции до начала и конца схватывани  с помощью прибора Вика по ГОСТ 125-80. Результаты испытаний даны в табл.2 и 3.The setting time of the dough is determined by the time from the beginning of the mixing of the composition to the beginning and end of the setting using the Vicat device according to GOST 125-80. The test results are given in table 2 and 3.

Как следует из таблицы, в жущее по изобретению имеет более высокую прочность при сжатии по сравнению с прототипом.As follows from the table, the inventive according to the invention has a higher compressive strength compared with the prototype.
