The mortar or concrete shall have a water soluble chloride ion content of less than 0.40 lb/cu yd (0.24 kg/cu m). The test shall be performed according to ASTM C 1218, and the mortar or concrete shall have an age of 28 to 42 days at the time of test. The ASTM C 1218 test shall be performed by an independent lab a minimum of once every two years, and the test results shall be provided to the Department. Mixing of the mortar or concrete shall be according to the manufacturer’s specifications. The Department will maintain a qualified product list. Art. 1019.01 Controlled Low-Strength Material (CLSM) SECTION 1019. Controlled Low-Strength Material (CLSM)
1019.01 Description. This work shall consist of the materials, proportioning,
mixing, and transporting of controlled low-strength material (CLSM).
1019.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Portland Cement, Type I ......................................................................... 1001
b.Water ...................................................................................................... 1002
c.Fine Aggregate for Controlled Low-Strength Material (CLSM) ........... 1003.06
d.Fly Ash .................................................................................................... 1010
e.Admixtures (Note 1) Note 1. The air-entraining admixture may be in powder or liquid form. Prior to approval, a CLSM air-entraining admixture will be evaluated in the laboratory by the Engineer. The admixture shall be able to meet the air content requirements of Mix 2. The Department will maintain a qualified product list.
1019.03 Equipment. Equipment shall be according to the following.
Item Article/Section
a.Concrete Mixers ................................................................................. 1103.01
b.Batching and Weighing Equipment .................................................... 1103.02
c.Automatic and Semi-Automatic Batching Equipment ......................... 1103.03
d.Mobile Portland Cement Concrete Plants .......................................... 1103.04
e.Water Supply Equipment ................................................................... 1103.11
1019.04 Mix Design Criteria, Mixing, and Proportioning. The mix design
shall meet the following criteria. Mix Design Criteria Parameter Value Flow ≥ 7 in. (178 mm) Air Content 0 – 25 % Dynamic Cone Penetration (DCP) at 3 days ≤ 1.5 in./blow (38 mm/blow) Compressive Strength at 28 and 180 days ≥ 30 psi (207 kPa) to < 150 psi (1034 kPa) The mix shall be produced according to Section 1020. The mixer drum shall be emptied prior to initial batch to ensure that no additional cement fines are incorporated into the mix. The Engineer reserves the right to adjust the proportions of the mix design in the field to meet the design criteria, provide adequate flowability, maintain proper solid suspension, and meet other criteria established by the Engineer.
