The compressive strength and splitting tensile strength are determined using the standard for transpor- tation 22TCN 22tnc are two types of recycled aggregates RAs from two different sources, RA from masonry debris called recycled masonry aggregate RMAand RA from concrete or concrete reinforcement structures called recycled concrete aggregate RCA. Log In Sign Up. RAs particles larger 5mm and smaller than 5mm at difference ratios were mixed and tested with various vibration time.

This has brought great benefits in terms of economic, engineering and environment aspects. Success is the ability to go from one failure to another with no loss of enthusiasm. Maximum dry density and optimum moisture content are determined using the standards for transpor- tation 22TCN Vibrating compacted density is determined in the following procedure: The results focused on effects of cement content on some subgrade proper- ties such as: Removal and Reuse of Hardened Concrete.
The community of me. Usually the CBR values are used by the pavement engineers to design the. Other criteria ID Document name.
In other cases 1. Learn from yesterday, live for today, hope for tomorrow. Click on stars to rate. This is not the same rules occurred with natural sand. Relations between compacted density of RMA 22cn vibration time Figure 6. Ministry Of Re- sources and Environment. CBR is frequently used as test value for civil crushed rock as a percentage value.
The California Bearing Ratio CBR test is a simple strength test that compares the bearing capacity of a material with that of a well-graded crushed stone thus, a high quality crushed stone material should have a CBR. Click here to register!
DIN 332-4 – 1990-06
The important thing is not to stop questioning. Such documents may concern. Relations between NFA, RAs sand and cement content – The compressive strength and splitting tensile strength of RAs sand increased as cement content increased, this is similar to the rules occurred with natural sand. Construction soil- Testing method for determine partical size distribution in labratory. Join Now Join Now. Remember me on this computer. There are no construction procedures and standards for testing as well as specifications of recycled CDW materials when they used for foundation layers and pavement road.

Happiness is when what you think, what you say, and what you do are in harmony. A some of resolutions to removate and reconstruct of the old damaged and degraded apartments in the big cities in Vietnam.
The re- sults are shown in Table 7. And 2t2cn compac- tion, the mortar in concrete and masonry was probable broken, resulted in increase of the density.

Koemer has described modified CBR aggregate systems in the modified CBR test carried out in mm diameter mould was also studied. The choice of materials for road-base and subbase are guided in TCVN
