Temperatures, Min. & Max.

An air temperature shall be recorded early in the morning for the minimum and around mid-afternoon for the maximum. Take the temperatures in a shaded area, otherwise they are meaningless. Temperatures are not required for structural concrete, except bridge decks.

 

Report No.

Start with the number 1 at the beginning of work for each project. The ending report number shall coincide with the last day each item is completed for paving and the last week for structural. Do not restart the report sequence if the project carries over to the next year.

Check Usage (Paving, Structural, Incidental, Patching)

Place an “X” in the appropriate box provided to indicate the type of work where the concrete is used.

 

Date (Mo./Day)

This column is only used for Ready Mix concrete applications. Enter the month and the date for each day of production during the week.

 

Example:          5/24, 7/01, 12/03, etc.

 

Mix Number

Enter the mix number being used that is listed in the proportion tables of IM 529.

 

Location- Station (Beg. /End/Dir)

Enter the beginning and ending station for concrete placed daily by mix. Enter the direction (N, S, E, W) for divided sections or B for 2-lane sections. For structural concrete enter the unit placed (Example: pier, cap, footing, deck). Enter item placed for other work. (Example: sidewalk, drive) The grade inspector will provide the location or item placed to the plant inspector.    

 

Batched

Enter the total cu. yds. batched for each mix for a paving plant. Enter the total cu. yds. batched for each unit poured for structures.

 

% Of Est. Used

Enter the percent of estimated concrete used. The grade inspector will provide the % of estimate used ((cubic yards used / cubic yards estimated) X100) to the plant inspector

 

Fine, Intermediate & Coarse Aggregate (Moisture)

Enter the percent moisture once in the morning and once in the afternoon for paving projects. Enter the percent moisture for each unit poured on structures.

 

Fine, Intermediate & Coarse Aggregate (T203 sp gr)

Enter the specific gravity for each aggregate listed in the T203 source tables.

 

Fine, Intermediate & Coarse Aggregate (Dry Wt.)

Enter the weight of each aggregate calculated by absolute volumes.

 

Actual Quantities Used Per cu. yds. (Pounds)

Cement     Enter the pounds of cement calculated by absolute volumes.

Fly Ash     Enter the pounds of fly ash calculated by absolute volumes.

GGBFS      Enter the pounds of GGBFS calculated by absolute volumes.

Fine           Enter the actual pounds of fine aggregate adjusted by moisture content.

Inter.         Enter the actual pounds of intermediate aggregate adjusted by moisture content.

Coarse      Enter the actual pounds of coarse aggregate adjusted by moisture content.

In Agg.      Enter the calculated difference between the actual weights and the dry weights of all aggregates.

Plant         Enter the average pounds of water added at the plant for each cu. yd., including ice

Grade        Enter the average pounds of water added on the grade (if permitted by specification).

 

Avg. W/C Ratio

Enter the ratio of total water, including water in the aggregates and water added on the grade, in one cu. yd. divided by the total sum of cement, fly ash, and ggbfs in one cu. yd., report to three decimal places.

 

CPI Gradations

This section of the report is for reporting the Certified Plant Inspector gradation test results for the coarse and fine aggregates being used in the mix.

 

Batched (Today or Week)

Place an “X” under the Today column if the report is being submitted daily (paving).

Place an “X” under the Week column if the report is being submitted weekly (structures).

 

Concrete Batched

Enter the total cu. yd. of concrete batched under the appropriate column. Paving plant totals are normally under the Today column; structural concrete totals are normally under the Week column.

 

To Date Total

Enter the running total for both concrete and cement.

Enter the T203 A number.

 

Remarks

Enter delays, which may take place. Enter description of noncomplying test results.

 

CPI

Enter the Certified Plant Inspector name and certification number.

Enter the plant monitor name and certification number.

 

If using the computer spreadsheet, most of this information will be entered on the Project Information and Mix Information sheets and automatically transferred to the Report. For QMC and BR mixes, the combined gradation will be calculated from aggregate percentages entered in the Mix Information Station From and To, Totals to Date Cement and Concrete, and Remarks will be entered directly on the Report.
