The present invention discloses an artificial stone slab, wherein the raw materials are mixed, pressed, and solidified, and the raw material comprises a main material and an auxiliary material. The main material, according to the total weight ratio of raw materials, comprises from about 20% to about 85% of particles containing hydroxide or metal oxide, from about 0% to about 50% of natural quartz, and from about 5% to about 25% of resin. The auxiliary material comprises a coupling agent and a curing agent, wherein the weight ratio of the coupling agent to the resin is from about 0.6:100 to about 2:100, and the weight ratio of the curing agent to the resin is from about 0.8:100 to about 1.2:100. The present invention also provides methods for manufacturing the aforesaid artificial stone slab. The present invention replaces natural quartz particles with particles containing hydroxide or metal oxide and ensures that the performance of the slab is up to standard, that the quality is more stable and easier to control, the decorative results are better, and finally, the mining of natural quartz is reduced by 10 times, achieving the objectives of greater environmental protection and lower costs. The resulting slab provides stable performance with good decorative results and thus saves resources and is conducive to environmental protection.

The invention relates to a hardenable multi-part acrylic composition. The composition has at least two parts which react with each other upon being mixed together to progressively harden to form a solid cement, such as a bone cement. The beads in the first part comprise an acrylic bead polymer core produced by suspension polymerisation and having a Tg of >70° C. and emulsion polymerised acrylic microparticles at least partially coating the surface of the acrylic bead polymer core. The microparticles may form a porous coalesced network. The bone cement composition comprises the first part and a liquid second part and optionally, further parts. The parts are operable to form a cement which hardens to a solid mass upon mixing of the parts together. The composition further comprises an acrylic monomer component in the second part and an initiator component. A method of production of coated beads for the hardenable multipart composition and a solid cement is also described.
