Description
Изобретение относитс к области исследовани свойств строительных материалов.The invention relates to the field of research of properties of building materials.
Известен сиособ онределени ирочности строительных материалов, например шамотных , путем изготовлени образца и испытани .The known method of determining the variability of building materials, such as chamotte, is by making a sample and testing.
Цель изобретени - усовершенствовать процесс онределени прочности и сократить его длительность.The purpose of the invention is to improve the process of determining the strength and reduce its duration.
Достигаетс это тем, что измер ют вес каждого образца и его анизотропию, определ емую отношением диэлектрических проницаемостей , измеренных на электромагнитных волнах диапазона СВЧ во взаимно перпендикул рных направлени х, за одно из которых принимают направление прессовани .This is achieved by measuring the weight of each sample and its anisotropy, determined by the ratio of dielectric constant, measured on the electromagnetic waves of the microwave range in mutually perpendicular directions, one of which is the direction of pressing.
Сущность способа заключаетс в следующем .The essence of the method is as follows.
Определ ют вес образца Р и измер ют вещественную диэлектрическую проницаемость образца в направлении прессовани EI и в направлении, перпендикул рном прессованиюThe weight of sample P is determined and the real dielectric constant of the sample is measured in the direction of pressing EI and in the direction perpendicular to pressing.
