The origin size of dolomite used in the preparation of poly art marble is 1.60–3.00 mm, while the kaolin powder was sieved with sieve opening size of 150 µm. Polyester resin and fillers were well mixed at 200 rpm using a planetary mixer for about 10 to 15 min until the fillers is fully wetted by the resin.

The mixing process consisted in dry mixing the powder compounds (kaolin clay, cement, sand) in the first stage, then adding the dry mixture into the corresponding water quantity, followed by mixing all the ingredients in a mortar mixer for 10 minutes.

The trends, since 1950, of the top ten clays (INCI names) in patent applications for cosmetics are shown in Table 4. Talc, kaolin, mica, and smectites are the clay minerals used most frequently in cosmetic products, with a sustained increase in their use, followed by other clay minerals. As with other industries, controversies exist about …

Moreover, since acrylic is more expensive than kaolin, utilizing kaolin substantially reduces the SAP synthesis costs. In our previous study [27], we synthesized SAPs comprising both an organic (∼acrylamide) and an inorganic (∼low-grade kaolin) component, and found that the liquid absorbency of the resultant SAP was less sensitive …

A GRCSE is a complex transportation infrastructure comprising foundation soft soil, columns, multiple layers of geosynthetic reinforcement, and embankment fill. ... each DCM column was precast by mixing kaolin clay slurry with Portland cement and fly ash to avoid the complex scale effects of in-flight jet-grouting improvement in centrifuge ...
