摘要： Methods for modifying a recycled fine powder of concrete and uses thereof. A method for modifying a recycled fine powder can include: crushing a collected waste concrete block with a crusher, grinding with a ball mill, and passing through a 100-mesh sieve, to obtain a recycled fine powder with d50 of 13.5 μm; placing the obtained recycled fine powder in a dry environment at a high temperature, drying, then taking out, and cooling to room temperature; preparing tannic acid solutions with different concentrations, mixing the cooled recycled fine powder with the prepared tannic acid solutions, and continuously stirring by a glass rod.

摘要： A concrete comprises in relative parts by weight: 100 of Portland cement; 0.25 to 9 of a defoamer; 0.001 to 6 of a surfactant; 0 to 230 of coarse gravel and/or fine gravel and/or shear enhancers; 0 to 85 of sand; 0 to 60 of a particulate pozzolanic or non-pozzolanic material or a mixture thereof having a mean particle size less than 15 micrometers; 0 to 80 of a particulate pozzolanic or non-pozzolanic material or a mixture thereof having a mean particle size between 15 to 88 micrometers; 0.3 to 18 of a water-reducing superplasticizer; 0 to 14 of polyethylene fibers; and 5 to 40 of water. An air mixing process using a tightly sealed mixing tool is used to thoroughly mix the constituents of the concrete before adding the water for curing. By adjusting relative parts in the composition, concretes of high and ultrahigh performance can be achieved efficiently.

摘要： The disclosure relates to methods of making asphalt concrete mixtures including reclaimed asphalt pavement (RAP). Variability in the fraction of binder that occurs in RAP that is able to melt and mix with virgin binder included in the concrete mixture previously made it difficult to select an appropriate amount of virgin binder. Methods described herein permit an asphalt concrete mix designer to determine the amount of virgin binder that can be combined with RAP and virgin aggregate in order to satisfy the minimum effective binder content of a job mix formula for such a concrete mix. The subject matter described herein thus permits more efficient use of RAP and permits use of RAP in higher amounts in asphalt concrete mixtures.

摘要： The invention is related to a device for the continuous mixing of lightconcrete comprising density decreasing particles, concrete and water, characterised by an elongated mixing chamber (1) in which a screw (4) is rotatably arranged around the central axis (5) of the cylinder (1). The screw is provided with two parts, a first transporting screw part (6) and a second combined transporting and mixing screw part (7). At the free end of the transporting screw part (6), a first feeding device (13) for the supply of density decreasing particles is arranged, and at the transition between the two different screw parts (6,7), a second feeding device (14) for the supply of a concrete/water mixture is arranged. The density decreasing particles are transported by means of the transporting screw part (6) into the combined transporting and mixing screw part (7), in-order to be mixed therein into a homogenous mass of at least density decreasing particles, concrete and water, and wherein at the same time, the mass is output from the free end of the combined transporting and mixing screw part (7). The invention is further related to a method of continuous mixing, and the use of a combined transporting and mixing screw.
