American Hydrosoil

Greetings from American Hydrosoil!

We are part of the Olive Trading Company with diverse interests in Tourism & Hospitality Industry of the US ; Metal & Mineral Trading; Food & Commodities Business.

We are pleased to offer Medium & Long Grain Rice from the USA as below:
Long Grain Raw Rice 5, 10, 15, 20, 25, 35, 100% broken
Long Grain Parboiled Rice 5, 10, 15, 20, 25, 35, 100% broken
Medium Grain Rice - Raw and Parboiled

We also offer RHA, or Rice Hull Ash, or Rice Husk Ash


Rice Husk ash insulating powder for ladle or tundish as FOB and CFR misurata ports.

RHA for use as a concrete additive for a superior concrete

RHA as a soil additive for moisture retention

RHA is a carbon neutral green product. Lots of ways are being thought of for disposing them by making commercial use of this RHA. RHA is a good super-pozzolan . This super-pozzolan can be used in a big way to make special concrete mixes . There is a growing demand for fine amorphous silica in the production of special cement and concrete mixes ,high performance concrete , high strength, low permeability concrete, for use in bridges, marine environments , nuclear power plants etc.

We manufacture organic micro-silica / amorphous silica, with silica content of above 89%, in very small particle size of less than 35 microns Silpozz for application in High Performance Concrete.


Other uses of Rice Husk Ash

This product can be used in a variety of applications like:

green concrete
high performance concrete
refractory
ceramic glaze
insulator
roofing shingles
waterproofing chemicals
oil spill absorbent
specialty paints
flame retardants
carrier for pesticides
insecticides and bio fertilizers etc etc.

Since it takes only a small amount of reactive aggregate to cause deterioration of concrete due to the alkali-silicate reaction, vast deposits of aggregates throughout the world are in danger of being rejected as undesirable for use in concrete unless acceptable corrective measures are found. Although addition of commonly available pozzolans can effectively reduce the expansion associated with the alkali-silicate reaction, the quantity of pozzolan needed for this purpose is generally large enough to influence adversely the water demand and thereby the concrete quality.

In this study the use of a highly active pozzolan, namely, rice hull ash, is compared with a normal pozzolan for reducing the alkali-silicate expansion. Whereas 25 percent of the latter by weight of the cementing material was required to reduce the expansion in the ASTM Test for Effectiveness of Mineral Admixtures in Preventing Excessive Expansion of Concrete Due to the Alkali-Aggregate Reaction (C 441-69) mortar by 90 percent, only 10 percent of the former was sufficient to obtain the same degree of effectiveness in reducing the expansion. Laboratory tests on concrete mixes containing the corresponding proportions of the pozzolans showed that, when compared with the control concrete, the mix containing the rice hull ash did not show strength loss at three and seven days whereas the mix containing the normal pozzolan showed severe strength loss at early ages.



We look forward to hearing from you. Your business is important to us and we promise to do due diligence on all your requirements and serve you faithfully.
