W Withheld to avoid disclosing individual company confidential data; included
with "Undistributed." 1 No sand and gravel production reported from the following
counties: Bartholomew, Benton, Brown, 
Clay, Crawford, Decatur, Dubois, Floyd, Jefferson, Jennings, Lawrence, Martin,
Monroe, Ohio, Orange, 
Perry, Pike, Ripley, Scott, Spencer, Tipton, Vanderburgh, and White. 
2 Includes production for which no county breakdown is available, and data
indicated by symbol W. 
 
 Over 49 percent of the output came from 10 counties, with Marion County
again ranking first. 
 About 92 percent of the sand and gravel was transported by truck, and most
of the remainder by rail. 
 
 Slag (Iron-Blast Furnace).—Slag, a byproduct of pig iron production
in Lake County blast furnaces, was used in manufacturing cement, mineral
wool, and roofing granules. Crushed slag was used as an aggregate and expanded
for lightweight aggregate. 
 At the Bethlehem Steel Corp. complex at Burns Harbor, large quantities of
blast furnace slag aggregate were used in the first phase of construction.
As the 5-year construction plan is developed, additional large quantities
of slag will be used as aggregate and for soil stabilization, roadways, and
railroad ballast. 
 Stone.—Total stone output reached a record high of nearly 27 million
tons valued at $46.7 million. Larger demand for crushed and broken limestone
for use in concrete aggregate, riprap, roadstone, and cement more than offset
decreases in demand for agricultural limestone and dimension limestone used
in building construction. 
 Salem limestone, which was the main source of Indiana building stone, was
quarried in Lawrence and Monroe Counties in the vicinity of Bedford and Bloomington.
Several of the building limestone quarries shipped about one-half million
tons of large rough blocks of stone for use as a breakwater for a Lake Michigan
port at Burns Harbor. This material is included in riprap mentioned previously.

 Crushed stone was produced from dolomites and limestones. The most important
