Dear Alex,
Sorry for being late but i had a discontinuity in the network. Regarding your problem I have several comments:
1- No specified concrete strength given to evaluate the stress
2- Rebound Hammer is not an accurate test
3- Cores results are very wide, I beleive you have problem in...
It is a new generation concrete that it may serve you in very low water to cement ratio and make your concrete flowable without segregation and to be selfcompacted be carefull for the dosage ask your expertise dealer fo admixture and preferable to do trial mixes at independant laboratory to...
The best way to estimate the settlement of soil is by conducting consolidation test matter and/or plate load. Since you are talking about peat thus organic soil and clayey materials are present i believe that plate load can do the job
AS previously mentioned by all our friends about the maximum time for revolution referring to ASTM C94 is OK.
But you should specify more whether the concrete used contains additives such as retarder and/or superplasticizer reatrder. In this case you should test the compliance of admixture and...
Dear Alex,
Please be informed that the proper way to verify the concrete compressive strength is by extracting cores of 4inch diameter and that complies with ASTM C42,
Whereas for the strength as i understood from your message that the concrete is poured since 14 days. My recommendation is to...
Dear Daniel,
To correlate the DCP with CBR you may use the book M.Y. Shahin (1994) “Pavement management for airports, roads, and parking lots”. Chapman and Hall
And to correlate the CBR with subgrade modulus uses the book Croney D, & Croney P. (1991). “The design and performance of road...
hi,
You can find the approximate optimum moisture content OMC of a soill for use in the compaction test from Johnson and sallberg (1962) p 125, or Engineering properties of soils and their measurement by Joseph E. Bowles. in compaction test procedure
