Test situation is as shown in the table:
The character of table 1 regeneration aggregate, natural rubble
Table 2 mix Design and mixture performance
Table 3 each numbering Concrete in Natural maintenance mechanical property of 28 days
Test explanation: regeneration aggregate adopts the waste concrete block in certain building removal, surveying particle diameter thereafter through broken, screening processing is 5-20mm, continuous grading. The test specimen that is numbered A0 is standard C 25 concrete benchmark test specimens, is numbered A20, A40, A60, A80, A100 test specimen is that regeneration aggregate replaces the concrete sample of making after natural rubble, and 20,40,60,80 is replacement rate.
Test result analysis:
Table 2 can find out, the ratio that replaces natural rubble along with regeneration aggregate increases, and concrete slump value reduces thereupon, and reason is that regeneration aggregate space is large, water absorption rate is high, causes the loss of the slump. In addition, concrete apparent density is also on a declining curve, and reason is that the apparent density of regeneration aggregate self is low, and this is of value to and alleviates concrete own wt, improves shock resistance.
As can be seen from Table 3, when the replacement rate of regeneration aggregate in concrete is controlled in the scope of 0-40%, regeneration aggregate is little on concrete compression strength impact, while adding 20%, also have more by a small margin and promote, reason is that the water absorption rate of regeneration aggregate is much larger than natural rubble, quite a few is reproduced aggregate absorption to add concrete mixing water, objectively reduce the concrete ratio of mud, can make up to a great extent the loss because adding the compression strength that regeneration aggregate causes, in addition, because regeneration aggregate corner angle are many, rough surface, increase frictional force, while making to destroy, speed slows down, thereby also improve concrete compression strength. but after replacement rate exceedes 40%, the character of regeneration aggregate has exceeded on the impact of compressive property the impact that the ratio of mud causes, causes the remarkable reduction of compression strength. in addition, along with the increase of substitute proportion, concrete resistance to compression bullet mould is decline state, illustrates that the fragility of regeneration concrete has reduced.
From the performance characteristic of above-mentioned regeneration concrete, the production that it is applied to Light trabs is highly beneficial. As little in the apparent density of regeneration concrete, good-extensibility, thermal conductivity factor is low, can alleviate building loading, plays antidetonation, fire prevention, heat insulation texts. The problems such as, resistance to compression tension high for regeneration concrete water absorption rate is poor, need on raw material, check on the one hand, need in technical recipe and technology of preparing, further investigate on the other hand, as regulate the ratio of mud, control regeneration aggregate mixed ratio, add water reducer, increase curing time etc., some defects that exist to make up regeneration concrete.
