A premixed photoluminescent composition and related hardened form and method of forming joints for pavers or stones. The premixed photoluminescent composition comprises solid aggregates; a photoluminescent particulate component adapted to emit light when photoexcited; and a binder. When in contact with an activator, oxygen or water, the binder is adapted to harden into a water-resistant binder matrix that bonds the solid aggregates and embeds the photoluminescent particulate component. In use, the water-resistant binder matrix has a transparency allowing transmission of at least a portion of the light emitted by the photoluminescent particulate component.

The invention relates to a method which enables sleepers to be produced for the railway track superstructure having optimised performance characteristics, in a reliable and cost-effective manner. The method according to the invention provides the following production steps: a) providing a mixture 10-60 % mass of which consists of a granulate of a plastic, which is deformable by applying heat, and the remainder of which consists of a sand having a bulk density of 1.4-2.0 g/cm.sup.3; b) heating the mixture to a temperature of 150-200 C.; c) pouring the mixture into a press mould reproducing the sleeper; d) pressing the mixture in the mould at a pressing pressure measured in the mixture of 1-5 MPa over a pressing period of up to 60 minutes; and e) removing the sleeper from the mould.

Disclosed are a stone-plastic floor and a method of preparing the same. The resin substrate of the stone-plastic floor of the present disclosure is prepared by using raw materials with specific components and amounts, without using any plasticizing agent, toughening agent and foaming agent and without environmental hidden dangers. The resulting stone-plastic floor has high strength, high hardness, excellent shrinkage performance and no environmental hidden dangers, and can tolerate direct sunshine, and has good stability and long service life for use safety. The method of preparing the stone-plastic floor of the present disclosure has simple processes, enabling online continuous production with high production efficiency.

A mounting pad system for securing equipment, such as an HVAC outdoor unit, is provided in the form of a lightweight fillable pad member having securing slots extending from an underside surface to an upperside surface of the pad member. Securing strap assemblies are associated with at least some of the securing slots and are insertable into the latter to secure the equipment therebetween. The pad member contains a filling port on its upper surface and is configured as a molded hollow shell containing a gelling material which, when mixed with water, provides support to reduce deflection of the pad member caused by the equipment secured to the pad, prevents damage to the pad that would otherwise be caused by the expansion of internal contents upon freezing and prevents leakage of internal contents of the fillable pad in the event of an unintended breach in the hollow shell. The pad member is provided with at least one through-hole for allowing a securing anchor to be inserted therethrough into the ground at the installation site without disturbing sealing integrity of the hollow shell.

A polymer masonry unit (PMU) and methods and systems for forming PMUs are presented. In embodiments, a PMU may be made from a PMU mixture of a polymer, a quarry byproduct, such as a limestone aggregate, and water. The PMU may be ambient-dried to become a brick unit. The proportions of the PMU mixture may include 1-10% polymer, 80-90% quarry byproduct, and 1-10% water. The process for making a brick using the PMU of embodiments may avoid a kiln-firing process, which is costly, creates waste, and consumes significant energy. Furthermore, the PMU mixture may be formulated to enable the PMU mixture to be extruded from an extruder, enabling a system for making bricks to take advantage of the extrusion method, which can be very efficient and cost-effective for making bricks, and which is currently not possible with existing techniques and systems.
