It is important to make use of composite sampling and to take at least five samples. Grab samples may be representative of flow during a short period and any other sample shown to be representative of waters being sampled may be applicable. The collection of samples for cyanide determination will require treatment to preserve the constituents.

Flowable fill is defined by the American Concrete Institute (ACI) as a self-compacting cementitious material that is in a flowable state at placement and has a compressive strength of 8.3 MPa (1,200 lb/in 2) or less at 28 days. Most current applications for flowable fill involve unconfined compressive strengths of 2.1 MPa (300 lb/in 3) or less.
SIEVE ANALYSIS AND FINENESS MODULUS Sampling Since the reason for sampling aggregates is to determine the gradation (particle size) of the aggregate, it is necessary that they be sampled correctly. The results of testing will re" ect the condition and characteristics of the .

Sampling Criteria Average Orchard (10-200 acre block. Spring or Summer Sampling) Collect sub terminal leaves from non-fruiting branches. Minimum of 13 trees each tree sampled at least 25-30 yards apart. In each tree collect 10 leaves around the canopy from well exposed branches located between 5-7 feet from the ground.

Sampling in layers of 0 to 2, 2 to 4, and 4 to 8 inches will help determine if tillage for lime incorporation is needed. Site-specific or Variable Rate Application Lime requirements vary within fields and can be mapped using grid soil sampling or, alternatively, by sampling zones within fields.

Sieve analysis determines the gradation or distribution of aggregate particle sizes within a given sample. Accurate determination of material smaller than 75 µm (No. 200) cannot be made with AASHTO T 27 alone. If quantifying this material is required, it is recommended that AASHTO T 27 be used in conjunction with AASHTO T 11.

Foundry sand testing is a process used to determine if the foundry sand has the correct properties for a certain casting process. The sand is used to make moulds and cores via a pattern.In a sand casting foundry there are broadly two reasons for rejection of the casting — metal and sand — each of which has a large number of internal variables.
