Abstract: Fast-setting Portland cement compositions for filling voids, such as mine shafts and excavated utility trenches, are described. The Portland cement compositions set quickly and are useful when traditional slow setting compositions are less desirable. The acceleration of the set time results from the addition of dry calcium chloride to the Portland cement composition. The compositions consist of Portland cement, dry calcium chloride, water and sometimes preformed cellular foam. Some compositions can include also include fly ash. The compositions may have a compressive strength of between 0 psi and 30 psi after 4 hours, a compressive strength of between 30 psi and 120 psi after 24 hours, a compressive strength of between 200 psi and 500 psi after 28 days, a penetration resistance of between 0.1 tsf and 5 tsf after 10 hours, a penetration resistance of between 0.8 tsf and 10 tsf after 24 hours, and a removability modulus of between 0.2 and 1.0 after 28 days. Also disclosed are methods of filling a void with fast-setting Portland cement.

Abstract: A seismic steel tubular column with internal local restraint and filled with high strengthen compound concrete containing normal-strength demolished concrete lumps, and a construction process. The seismic column includes a steel tube (1), high-strength fresh concrete (2), normal-strength demolished concrete lumps (3), horizontal stirrups (4), and longitudinal erection bars (5). The horizontal stirrups (4) are arranged at upper and lower ends inside the steel tube (1). The high-strength fresh concrete (2) is poured and the normal-strength demolished concrete lumps (3) are put alternately inside the steel tube (1). A compressive strength of the high-strength fresh concrete (2) is 30˜90 MPa greater than that of the normal-strength demolished concrete lumps (3).

Abstract: A process for making a composite pavement structure comprising primed glass aggregate particles and a polymeric binder composition is disclosed. Systems and methods are also disclosed for the priming of glass aggregate particles. In one embodiment, the glass aggregate particles range from about 0.1 to about 0.5 inch in diameter and are exposed to a coupling agent in solution, for example an aqueous aminosilane solution, in an amount of about 1 to about 10 parts by weight of solution based on 100 parts by weight of the glass aggregate particles wherein the aqueous solution contains about 0.01 to about 5.0 parts by weight coupling agent based on 100 parts by weight of solution. After exposure, the primer is allowed to react and bond with the glass aggregate particles for a predetermined time period to provide primed glass particles, for example silylated glass particles, which are then dried. Once the primed glass and polymeric binder composition are mixed, they are allowed react and bond to provide a composite pavement structure.
