Durable high early strength concrete
… $0.8 and $1.15 million dollars per lane mile. High early strength Portland cement concrete pavement (PCCP) patches are widely used in pavement preservation in Kansas due to the ability to open to traffic early. However, these repairs done by the Kansas Department of Transportation (KDOT) …

Towards performance engineered specifications for high early strength concrete pavement repair applications
… transportation agencies. Repair of concrete highways is necessary whenever there is a distress area that, if not properly addressed, would propagate, ending up reducing the service life of the infrastructure and the quality of the ride. Due to the need of quickly re-opening the infrastructure …

An investigation of the characteristics of high alumina refractory castables
… of the refractories family, are an admixture of highly aluminous cements and graded refractory aggregates, blended in predetermined proportions very much like structural concrete. The refractory aggregates must contain a large amount of fines contrary to the requirements of ordinary concrete. …

Estabilização de areia com cinza volante e cal; efeito do cimento como aditivo e de brita na mistura
… cement and crushed stone on the compressive strength of the mix. In order to enhance fly ash role the soil chosen was a non-cohesive one - a uniform dune sand - which is not quite suitable for stabilization with cement and not at all with lime. Stabilization effect results from cementation of …

An investigation of the effects of abnormal curing conditions on Dolomitic limestone Portland cement concrete
… as follows: 1. Fresh concrete continues to gain strength while in the frozen state. 2. Freezing and then thawing of fresh concrete does not have an appreciable effect on the twenty-eight day ultimate strength, and the concrete, if given time to recover, will compare favorably with concrete cured …

Development of a New Cold Binder Course Emulsion Asphalt
… emulsion mixtures (CBEMs). However, to date, low early life stiffness, a slower rate of curing, the length of time necessary to achieve full strength, high air void contents and the presence of moisture in these mixtures have prevented them from being fully embraced by pavement authorities. This …

Evaluation of Resistivity Meters for Concrete Quality Assurance, Project TR201414
… also demonstrated low permeability as well as high compressive strength with an average value of over 9,000 psi at 90 days. The two repair mixtures showed moderate to low penetrability readings and high early strength consistent with their desired purpose. Tests were also performed on a series …

Development of a New High Performance Cold Mix Asphalt
… internationally. The majority of roads and highways are paved using hot mix asphalt (HMA) technology. The manufacture of hot mix asphalt is a key source of energy consumption, greenhouse gas emissions and air pollution. As such, efforts have been made to develop sustainable techniques to …
