A process for making a pervious concrete comprising a geopolymerized pozzolanic ash. Generally, the process includes mixing a solid aggregate and a geopolymerized pozzolanic ash binder together to form a pervious concrete mixture. Some examples of suitable aggregates comprise recycled carpet, recycled cement, and aggregates of coal-combustion byproducts. The geopolymerized pozzolanic ash binder is made by combining a pozzolanic ash, such as fly ash, with a sufficient amount of an alkaline activator and water to initiate a geopolymerization reaction. The activator solution may contain an alkali metal hydroxide, carbonate, silicate, aluminate, or mixtures thereof. In some aspects, the final concrete forms a solid mass in the form of pavement or a pre-cast concrete shape. The solid mass of concrete may have a void content of between about 5% and about 35%.

Novel premium blended pozzolans for use with hydraulic cement are created by intergrinding an ASTM Class F or Class C coal fly ash and a source of calcium sulfate, such as gypsum, so that the resultant mixture has a fineness of at least 90% passing through a 45 micron sieve. The novel mixture meets the requirements of ASTM C 618. Alternately, a novel concrete composition can be formed using the blended pozzolan with a hydraulic cement, aggregate and water so as to produce a concrete having improved strength, ASR mitigation, improved sulfate resistance and lowered permeability. The novel pozzolans not only reduce production costs by decreasing fuel and raw material consumption per ton of cement, but they also use by-product waste materials from another industry to create a premium product for the construction industry.

Novel solutions, which can include devices, systems, methods, than can measure earthquakes and other displacement events. Some solutions feature the integration of real-time, high-rate global navigation satellite system (“GNSS”) displacement information with acceleration and / or velocity data within a single device to create very high-rate displacement records. The mating of these two instruments allows the creation of a new, very high-rate displacement measurement device that has the full-scale displacement characteristics of GNSS and high-precision dynamic motions of seismic technologies. Such a device can be used for earthquake early warning studies and other mission critical applications, such as volcano monitoring, building, bridge and dam monitoring systems.

Thermoplastic products such as vehicle cargo area liners, floor mats, recreational and playground equipment, cargo pallets, and wet area walking surfaces are provided with an antislip surface treatment. The antislip surface is made up of individual non-interconnected asperities of an antislip polymer material, which do not form a continuous film over the surface of the thermoplastic product. The thermoplastic product is especially made of high density polyethylene. The antislip polymer is preferably a thermoset polymer, and most particularly is a polyurea / isocyanate polymer. The antislip polymer is preferably applied by spraying, and then the product is heat treated at a temperature in the range from 100 to 200° F., or is thermoformed at a temperature in the range from 250 to 550° F. The antislip asperities are durably bonded onto the thermoplastic base material, and provide a significantly increased coefficient of friction. The asperity size, height, and hardness can be controlled by adjusting the processing conditions. The asperities may have an increased surface relief due to a so-called "moth effect" and an increased surface roughness due to cratering as a result of a so-called "volcano effect" in the process using thermoforming.

This invention pertains to a process of making ASTM quality masonry cement, mortar cement, and stucco cement (also called plastic cement) and to the products themselves which are useful in making ASTM quality mortar for masonry construction or ASTM quality stucco for plastering construction.

An apparatus controls the evacuation of volcanic magma to prevent explosions. Magma evacuation is through a single evacuation tube that heats the magma flow within the tube to prevent stickiness of the magma in the tube. The heating may use small combustion chambers to heat steam, which in turn heats and stabilizes the magma flow. Stability is aided by central cooling, where needed, using water jets from nozzles located at the wall of the tube.

This system of the control and protection of the terrestrial climate relies mainly on civilian airlines burning (preferably price-subsidized) sun-shading (sun-blocking / sun-reflective) fuels in the high levels of the atmosphere in order to reduce the intensity of the solar radiation reaching the Earth's surface. The use of sun-blocking airline fuels for the protection of the Earth from solar radiation parallels the use of sun-blocking skin-creams for the protection of the individual. The invention parallels the cooling effect on the Earth's climate caused by major volcanic eruptions, collisions of the Earth with asteroids, or the cooling effect one could expect after a major nuclear war. This invention proposes the creation of a controlled mini “nuclear winter”, in other words of a cooling caused by the increased refraction of the atmosphere or by the increased shading of the terrestrial surface by particulates in the high levels of the atmosphere.
