Definitions
- This invention relates to controlled low-strength mixtures (CLSMs), or flowable back fills. More particularly, this invention relates to a composition and method for making such a mixture using a hemi-hydrate gypsum, or related compounds such as a variety of soluble or sparingly-soluble calcium sources such as calcium salts of chloride, oxide, hydroxide, acetate formate, citrate, alkyl or aryl sulfonates and alkyl, alkenyl or aryl carboxylates, in combination with a pozzolanic material, typically a fly ash material, to produce a quick set, low strength, flowable fill.
- a pozzolanic material typically a fly ash material
- Flowable fill products that use an ASTM Class C fly ash or Portland cement mixture are commercially available, such as K-KRETE, M-CRETE, S-CRETE, FLOWABLE FILL, FLASH FILL, ONE-SACK MLX, and FLOWABLE GROUT.
- Products using Class C fly ash as the cementitious agent take advantage of the quick lime content found in this ash to obtain a quick hydration set and have diluted the ash with aggregates to keep the compressive strength in the 200-400 psi range.
- This class of materials has utility as pipe bedding materials where they are used to both protect the pipe from external agents and internal loads. They have also been used as an erosion barrier in embankments and as a mine fill material.
- CLSMs typically have strengths of less than 2000 psi and in cases where removal is contemplated, less than 200 psi for ease of removal.
- the material is initially in the form of an easily pumpable and self-leveling slurry. Rapid early strength development (approximately 50-70 psi) is a desirable property and is currently not obtainable with commercial products without the penalty of high strength development at later stages.
- Rapid early strength development approximately 50-70 psi
- Class F ash has been used in flowable fills mixed with cementitious materials to obtain low compressive strengths over time with no requirement for a quick set.
- cementitious materials are used from 5-13% by weight for Portland cement and from 5-20% for Class C fly ash with the remainder being various forms of aggregate, usually fine sand or soil from the spoil with small amounts of additional rock and gravel.
- These materials may take several days to achieve a modest strength of 50 psi; typically the minimum strength required for a man to walk upon the surface of the bedding material. This also represents a minimum safe strength before a cover fill may be placed.
- a CLSM or flowable fill system that minimizes the down time before cover fill may be placed represents a significant savings of both time and money for the user.
- An early modest strength and moderate ultimate strength are both requirements of a flowable fill ideally designed into the material properties of most systems.
- the ability to tailor both the time to achieve a sufficient early strength and a moderate ultimate strength represents a significant improvement to existing flowable fill systems.
- None in the prior art teaches or discloses the ability to obtain early low strengths (less than 1 hour at around 60-80 psi) using Class F ash and still maintain these strengths low over time.
- the present invention offers this significant improvement. Additionally, The present invention opens a huge market for the millions of tons of "off spec" Class F fly ash produced annually.
- SUMMARY OF THE INVENTION Gypsum hemi-hydrate, commonly known as Plaster of Paris, when combined with water has been used for centuries as a rapid-setting plaster.
- the calcium-rich phase may be the gypsum phase or, alternatively, may be chosen from a variety of soluble or sparingly-soluble calcium sources such as calcium salts of chloride, oxide, hydroxide, acetate, formate, citrate, alkyl or aryl solfonates and alkyl, alkenyl or aryl carboxylates.
- the rate of sfrength gain from the pozzolonic reaction can be tailored by the appropriate choice of the amounts and type of a pozzolonic accelerator such as sodium hydroxide.
- a system that can achieve a sufficient early sfrength of 50 to 100 psi, due essentially to a hydration reaction, using small amounts of gypsum hemi-hydrate in combination with an alkali metal hydroxide or carbonate as a pozzolonic accelerator will yield a system that has both the advantage of early moderate sfrength and a controllable, longer term sfrength enhancement from the subsequent pozzolonic reaction.
- the present invention therefore, provides a material which acts like compacted soil within 30 minutes from initial pouring and over an extended period of time and which may be excavated with normal earth moving equipment when, or if, the need occurs.
- normal ASTM C-618 F fly ash is not required to accomplish the desired results and that "off spec" Class F fly ash pozzolan powder may be utilized.
- the flowable fill composition of the present invention is a fly ash pozzolan material in the range of about 40% to about 80% by weight mixed with a hemi-hydrate material in the range of about 1% to 20% in an aqueous mixture, wherein the composition is characterized as having a quick set compressive strength of approximately 60-300 psi within less than one hour from the time of mixing.
- the fly ash used in the present invention may be designated ASTM C-618 material or non-ASTM material meeting the mineralogical criteria of a Class F fly ash.
- the gypsum in concentrations of 1-9% of the weight of the powder composition, with the pozzolan representing the remaining 91-99% of the powder weight gives the mixture a quick set of about 15-30 minutes because of gypsum hydration. This quick set time is controlled to maintain around 60-300 psi within the first hour. After this time the gypsum has hydrated and will not contribute to any continued compressive strength gain. Should the user require the use of other aggregate such as sand or other rock, a higher concentration of gypsum to Class F fly ash pozzolan powder in the 10-20% by weight of powder range may be used.
- the present mvention makes use of ASTM Class F fly ash pozzolan powder and off spec Class F pozzolan powder withhemi-hydrate gypsum and other anhydrate products to create a 1 low cost, low strength (100-300 psi), quick set — less than 30 minute — flowable fill material.
- the material is comprised of 91 -99% (by powder weight) pozzolan and 1 -9% (by powder
- 6 hemi-hydrate gypsum combination may be raised as high as 10-20% of the weight of the
- Example 1 0 Cool fly ash, Type F, was obtained from a paper recycling plant and used as received. 1 To 165 grams of this ash was added 15 grams of gypsum hemi-hydrate, 30 grams of lime 2 kiln dust, and 90 grams of silica sand. The dry ingredients were mixed well and 110 grams of
- Cool fly ash, Type F was obtained from a paper recycling plant and used as received.
- fly ash was obtained from a coal-fired utility plant and screened
- Example 3 To 510 grams of the +200 ash were added 60 grams of lime kiln dust and 30 grams of gypsum hemi-hydrate. To these dry ingredients was added 139 grams of water. The resulting mixture was very thin and pourable, setting in 7 minutes. The 3-day strength was 75 psi and the 33-day strength was 1953 psi.
- Example 4 To 510 grams of the +200 ash were added 60 grams of lime kiln dust and 12 grams of gypsum hemi-hydrate. To these dry ingredients was added 136 grams of water. The resulting thin mixture set in 22 minutes. The 3-day sfrength was 41 psi and the 33-day strength was 477 psi.
- Example 5 To 570 grams of ASTM C-618 Type F fly ash was added 12 grams of gypsum hemi- hydrate and 136 grams of water. The thin mixture set in 13 minutes. The 28-day strength was 285 psi.
- Example 6 To 400 grams of ASTM C-618 Type F fly ash was added 400 grams of ASTM Type C- 33 silica sand and 12 grams of gypsum hemi-hydrate. To this was added 88 grams of water. The mixture set in 9 minutes and had a 3-day sfrength of 59 psi.
- Example 7 To 400 grams of ASTM C-618 Type F fly ash was added 200 grams of ASTM C-33 silica sand and 12 grams of gypsum hemi-hydrate.
