HIGH PERFORMANCE PRETENSIONED SPUN HIGH STRENGTH CONCRETE PILES WE DELIVER Introduction LOCATION OF ICP FACTORIES IN MALAYSIA Perlis INDUSTRIAL CONCRETE PRODUCTS SDN BHD (ICP) is the first commercial manufacturer of Kedah PRETENSIONED SPUN CONCRETE PILES (ICP PC PILES) in Malaysia. Presently, ICP is the largest manufacturer in South East Asia. ICP Piles are Pulau Pinang circular hollow in cross-section and are manufactured in sizes ranging from diameter Kelantan Terengganu Perak 250mm to 1,200mm with lengths varying from 6m to 46m in single piece. For large diameter piles, ICP has pile joining facility which is able to pre-join the piles up to 70m. ICP Piles are exported to Brunei, Singapore, Pahang Bangladesh, Sri Lanka, the Middle East, Selangor Indonesia, Pakistan, Philippines, Vietnam, Myanmar, USA, Canada, New Zealand, Maldives and Samoa. ICP Piles are also supplied to Kuala Negeri numerous projects in Southern China from our Lumpur plant in Jiangmen, China. Sembilan Melaka AREAS OF APPLICATION Johor Bridges Marine Structures Piled Embankments Civil Engineering Works Building Foundations Heavy Industries High rise, school and government projects. Singapore PRODUCT ATTRIBUTES Steam curing enables faster High strength concrete up to grade Environmental friendly installation production rate and delivery to 100 enables piles to be driven by hydraulic jacking equipment project sites. through hard strata. which is free of noise, air pollution and vibration. Can be customized to suit project Can be manufactured up to requirements. diameter 1200mm and a maximum Prestressed concrete provides single length of 46 metres. higher bending moment capacity Spinning process results in more Big diameter piles can also be joined compared to conventional durable concrete with high in factory up to the length of 70m. reinforced concrete piles. resistance to corrosion. 1 General Specification STANDARDS IDENTIFICATION ICP PHC Piles comply with MS 1314:Part 4:2004 and also All ICP PHC Piles have the typical generally complies with JIS A 5337:1987. ICP PHC Piles markings as below: are modified to suit BS 8004:1986 – Foundations and BS 8110:1997 – Structural Use of Concrete. Concrete Company’s Initial ICP complies with SS EN 206-1:2009 - Specification Malaysian Standard MS1314: Pa 4 of Concrete. Pile Size and Class 60B800 Date of Cast (yy/mm/dd) 130917 MATERIALS Serial No & Factory Code 001L3 Aggregates – Coarse aggregates shall be 20mm granite. Pile Length and Type 12E Fine aggregates shall be clean river sand or washed Logo as Trademark mining sand. Other markings: Cement – Portland cement complies with MS 522:2007. S - Starter (Flat Shoe/X-Pointed Shoe/ Prestressing Steel – High frequency induction heat Rock Shoe/Pipe Shoe) treated bars manufactured to JIS G 3137:1994 or equivalent. E - Extension Spiral Wire – Hard drawn wire. B8 - Class B, Grade 80 B9 - Class B, Grade 90 CONCRETE STRENGTH BX - Class B, Grade 100 Minimum concrete cube strength: STANDARD LENGTHS at transfer of prestress 30N/mm2 ICP PHC Piles are available in lengths of 6m to 46m at 28 days - Grade 80 pile 80N/mm2 subject to certain limitations. - Grade 90 pile 90N/mm2 - Grade 100 pile 100N/mm2 DELIVERY ICP Standard Piles are normally available ex-stock. Custom made piles usually takes two to three weeks JOINT from date of confirmed order. The joint is designed to have the same performance as the main body particulary in respect of bending TECHNICAL DATA strength. All ICP PHC Piles have steel extension plates Technical data of our standard piles are given in the for splicing. tables on the next page. Please note that the axial loads represent the structural capacities of the piles. LIFTING POINTS Actual working load depends on the soil conditions and For piles up to 12m length, piles shall be lifted by using the pile slenderness ratio. Appropriate reduction steel hooks at both ends. For piles exceeding 12m, piles of axial loads should be applied for: shall be lifted by wrapping wire ropes around the piles a) marine structures; at the marked lifting points. b) piles subjected to bending; c) high upstand; PILE SHOE d) piles driven through very poor top stratum; All ICP PHC Piles will be supplied either open ended, e) raking piles, etc. with a flat shoe or with an X-pointed shoe. DEFINITIONS CURING ICP PHC Piles: High Performance Pretensioned Spun After casting, the piles are steam cured. When the High Strength Concrete Piles concrete reaches the specified transfer strength, the MS: Malaysian Standard piles are demoulded, marked and checked for quality. JIS: Japanese Industrial Standard The piles can normally be transported and driven after BS: British Standard three days from the date of casting, or when the cube SS EN: Singapore Standard strength reaches 70 N/mm2. 5 2 Properties Of ICP Piles STANDARD GRADE 80 PILES CLASS A (EFFECTIVE PRESTRESS ≥ 4.0 N/mm2) Recommended Max Nominal Nominal Nominal Prestressing Bar Area of Bending Moment Length Section Structural Axial Working Eective Diameter Thickness Weight Concrete 7.1mm 9.0mm Modulus Cracking Ultimate L oad (For a short strut) Prestress mm mm m kg/m no . no. mm2 x1000 mm3 kNm kNm ton N/mm2 350 60 6-12 142 8 - 54,664 3,533 32.9 54.1 104 5.3 400 65 6-12 178 8 - 68,408 5,106 42.7 61.8 132 4.3 450 70 6-12 217 10 - 83,566 7,113 60.4 86.9 161 4.5 500 80 6-12 274 12 - 105,558 9,888 82.3 115.9 204 4.3 600 90 6-12 375 - 12 144,199 16,586 148.8 222.5 276 5.0 2 C LASS B (E FF ECTIVE PRES TRESS ≥ 5.0 N/mm ) Recommended Max Nominal Nominal Nominal Prestressing Bar Area of Bending Moment Length Section Structural Axial Working Eective Diameter Thickness Weight Concrete 7.1mm 9.0mm 10.7mm Modulus Cracking Ultimate L oad (For a short strut) Prestress mm mm m kg/m no. no. no. mm2 x1000 mm3 kNm kNm ton N/mm2 250 55 6-12 88 6 - - 33,694 1,435 14.9 29.0 63 6.4 300 60 6-12 118 7 - - 45,239 2,383 22.9 40.6 86 5.6 350 70 6-12 160 9 - - 61,575 3,778 35.6 60.8 117 5.4 400 80 6-15 209 12 - - 80,425 5,643 53.7 92.7 153 5.5 450 80 6-15 242 - 8 - 92,991 7,624 70.0 111.2 177 5.2 500 90 6-15 301 - 10 - 115,925 10,518 95.9 154.5 221 5.1 600 100 6-15 408 - 14 - 157,080 17,546 163.1 259.6 299 5.3 700 110 6-18 530 - 20 - 203,889 27,131 265.1 432.6 386 5.8 800 120 6-18 667 - 24 - 256,354 39,455 376.8 593.3 487 5.5 900 130 6-18 818 - 28 - 314,473 54,942 510.3 778.7 599 5.3 1000 140 6-18 983 - - 24 378,248 74,056 688.9 1042.8 720 5.3 1200 150 6-18 1286 - - 36 494,801 120,188 1198.5 1877.1 934 6.0 2 CLASS C (EFFECTIVE PRESTRESS ≥ 7.0 N/mm ) Recommended Max Nominal Nominal Nominal Prestressing Bar Area of Bending Moment Length Section Structural Axial Working Eective Diameter Thickness Weight Concrete 7.1mm 9.0mm 10.7mm 12.6mm Modulus Cracking Ultimate L oad (For a short strut) Prestress mm mm m kg/m no. no. no. no. mm2 x1000 mm3 kNm kNm ton N/mm2 250 55 6-12 88 7 - - - 33,694 1,443 16. 2 3 3.8 63 7.2 300 60 6-12 118 10 - - - 45,239 2,416 28.0 57.9 84 7.6 350 70 6-15 160 - 8 - - 61,575 3,826 43.0 86.5 114 7.2 400 80 6-15 209 - 12 - - 80,425 5,748 69.7 148.3 147 8.1 450 80 86.9 166.9 6-15 242 - 12 - - 92,991 7,734 173 7.2 500 90 6-18 301 - 15 - - 115,925 10,670 120.3 231.7 215 7.3 600 100 6-30 408 - 20 - - 157,080 17,761 196.4 365.0 292 7.0 700 110 6-46 530 - - 20 - 203,889 27,498 320.6 608.3 376 7.6 800 120 6-46 667 - - 24 - 256,354 39,966 454.7 834.3 475 7.4 900 130 6-46 818 - - 28 - 314,473 55,622 617.7 1095.0 584 7.1 1000 140 6-46 983 - - 36 - 378,248 75,188 864.5 1564.3 699 7.5 1200 150 6-36 1286 - - 46 - 494,801 121,361 1378.6 2398.6 916 7.3 1000 140 6-4 6 983 - - - 34 378,248 76,247 961.1 20 51.9 688 8.6 1200 150 6-3 6 1286 - - - 46 494,801 123,457 1 583.1 33 31.3 898 8.8 N = ƒca x A FORMULA FOR AXIAL LOAD = 1/4 (ƒcu - ƒpe) x A Based on BS 8004: 1986, the maximum allowable axial stress that may be applied to a pile acting Where, ƒca = permissible compressive as a short strut should be one quarter of specified N = maximum allowable strength of concrete works cube strength at 28 days less the prestress axial load ƒcu = specified compressive after losses. = cross section area of strength of concrete concrete ƒca ƒpe = eective prestress in concrete 3 STANDARD GRADE 90 PILES CLASS A (EFFECTIVE PRESTRESS ≥ 4.0 N/mm2) Prestressing Bar Bending Moment Recommended Max Nominal Nominal Length Nominal Area of Section Structural Axial Working Eective Diameter Thickness Weight Concrete Modulus Prestress 7.1mm 9.0mm Cracking Ultimate L oad (For a short strut) mm mm m kg/m no .
