plant at the time the aggregate samples are collected from the working faces of the stockpiles. After performing gradation testing for each aggregate sample, the combined aggregate gradation is calculated according to the form instructions. Record project data on department worksheet WS3012, Combined Concrete Aggregate Gradation.
The goal for the new 47BR Combined Aggregate Gradation is to have the contractor, with agency oversight, develop a concrete mix design with an optimum combined aggregate gradation and provide the Contractor with the testing and control responsibilities to ensure
detrimental for portland cement concrete or other intended usages. ** A flat or elongated particle is defined as one having a ratio between the maximum and the minimum dimensions of a circumscribing prism exceeding five to one. 901-1.4 Gradation: Coarse aggregates shall conform to the gradation …
Two full-scale ready-mix concrete trials were tested in December of 2009. These two mixes followed the proposed 47BR combined gradation shown in Figure 2. The testing of each specimen met the specified requirements in Table 3. Each specimen was tested by the NDOR Portland Cement Concrete laboratory at the Materials & Research facility in
Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
If the soil material does not have gradation and Atterberg limits similar to the soils specified, the contrac-tor shall provide soil-cement, moisture-density relations data, Atterberg limits, gradation tests, and either The mixing plant shall produce a mixture of soil, cement, and …
