Description
Уже известны способы определени удобоукладываемостн бетоннон массы, основанные или на опускании (без удара) пуансона в испытываемую массу свелчбго бетона или на определении продолжительности его вибрировани .There are already known methods for determining the workability of concrete mass, either based on lowering (without impact) the punch into the test mass of the softened concrete or on determining the duration of its vibrating.
Недостаток указанных способов заключаетс в том, что показани , получаемые в результате испытаний, завис т от консистенции испытываемой бетонной массы и примен емых снособов ее уплотнени .The disadvantage of these methods is that the indications obtained as a result of the tests depend on the consistency of the concrete mass to be tested and the methods used for its compaction.
Предлагаемый способ определени удобоукладываемости бетона основан на определении степени уплотнени бетона по количеству работы , необходимой дл уплотнени .The proposed method for determining the workability of concrete is based on determining the degree of compaction of concrete according to the amount of work required for compaction.
Сущность предлагаемого способа заключаетс в следуюш,ем.The essence of the proposed method is as follows.
Испытуемый образец бетона укладывают без уплотнени в открытый сверху сосуд, заполн его бетоном вплоть до верхних краев . Над сосудом устанавливают копер или иное известное устройство, снабженное подвижным пуансоном и падаюш.им на него грузом определенного веса (например, 5 кг).The test sample of concrete is laid without compaction into an open vessel on top, filling it with concrete up to the upper edges. A pile driver or another known device fitted with a movable punch and a weight of a certain weight (for example, 5 kg) on it is placed over the vessel.
В процессе испытани иуансон, опуш,енный вплоть до соприкосновени с поверхностью бетона, подвергают действию груза, падающего на него с определенной высоты (например, 20 см), отмеча но градуированной щкале или по отметкам на самом пуаисоне его погружение на определенную глубину.In the course of testing, a downhill, down to contact with the concrete surface, is exposed to a load falling on it from a certain height (for example, 20 cm), marked with a graduated scale or marks on the puaison itself to its immersion to a certain depth.
Мерой удобоукладываемости служит количество работы, затрачиваемой на погружение в бетон пуансона, определ емой по качеству ударов груза, совершающего при каждом падении определенную работу, например, в данном примере килограммо-метр.A measure of workability is the amount of work expended on immersion in the concrete of the punch, determined by the quality of the impact of the load, making a certain work with each fall, for example, in this example, a kilogram-meter.

Способ определени удобоукладываемоети бетона, отличающийе тем, что удобоукладываемость определ ют по количеству работы, затрачиваемой на уплотнение испытуемой массы при погружении в нее пуансона на определенную глубину под действием падающего на пуансон груза, /The method for determining the workability of concrete, characterized in that workability is determined by the amount of work expended on compacting the test mass when a punch is immersed in it at a certain depth under the action of a weight falling on the punch.
