  1. 1. CONCRETEDATASHEET Agilia™ Horizontal’s finishing characteristics and high quality surface finish eliminate the need to power float concrete on site. Applications Slabs Residential dwelling oversite / slabs Structural toppings Domestic floors Commercial slabs such as composite deck construction (rib metal decking) Low traffic industrial floor slabs Mezzanine & office areas within industrial units Characteristics Agilia™ Horizontal enables the rapid and effortless fabrication of slabs and floors. Lafarge technology means that surface finish is of high quality. This can eliminate power-floating on site. Floor finish tolerance to BS 8204 – 1 SR2. Agilia™ is proven to improve your construction processes, after extensive research with Loughborough University1, 2 . Research focused on determining and clarifying the exact benefits that Agilia™ can bring to the construction process. The research made it clear that Agilia™ is not just a material for construction but it is in fact a method of construction. By adhering to the Agilia™ method significant savings were shown to be achievable. Placement with Agilia™ can reduce slab construction time by nearly 75%. Whilst also reducing the gang size from four operatives to two. 1 Research undertaken by the Centre for Innovative and Collaborative Construction Engineering at Loughborough University to explore and quantify the effects of SCC in construction. 2:30 Agilia™ Conventional Placement* time of 1m2 of concrete Construction time (mm:ss) *Where placement includes discharge, tamping, screeding, levelling and with reference to Agilia™ , dappling 2:152:001:451:301:151:000:450:300:150 0:36 2:16 ©DaveBird/TristanPoyserPhotography©DaveBird/TristanPoyserPhotography©DaveBird/TristanPoyserPhotography
  2. 2. Installation Agilia™ Horizontal can be laid over any stable substrate. Bond to substrate When the concrete is laid unbonded to the substrate, a polythene membrane of suitable thickness will be required. When the concrete is to be laid bonded, steel reinforcement mesh will be required. Bonding compound (such as an SBR type product) to be applied. Perimeter isolation A compressible strip with a minimum thickness of 5mm and maximum of 15mm should be fixed around the walls. The isolation strip is required to be fixed around vertical features such as columns and pipe ducts. Particular attention must be taken at re-entrant angles such as doorways, bays and alcoves. Ensure the perimeter isolation is placed at right angles into all corners of the room. On exterior angles it may be necessary to double up the isolation to ensure that the minimum thickness is maintained around the angle. The most suitable material for this is a self adhesive ethafoam strip; a small amount of steel mesh should also be placed around any internal corner or extrusion through the slab. Substrate preparation In all cases, a polythene membrane of 150μm minimum thickness and 350μm maximum thickness must be laid on the substrate. Agilia™ Horizontal is highly fluid and this requires the membrane to be substantially watertight to prevent loss of material. The sheet should be laid with a 300mm overlap, adhesive tape at least 50mm wide should be applied along overlapping joints of the sheets to seal them. Care should be taken to ensure the membrane is folded, or cut and sealed, into a corner. Around the perimeter of the room, the edges of the polythene membrane should extend well above the intended level of topping or should be taped to the ethafoam strip. Agilia™ Construction Method Removal of the power floating operation reduces an aspect of the variability and unpredictability with concrete slab construction. Agilia™ increases the predictability of construction projects with respect to project time and costs, reducing the risk of unforeseen expenses and delays. In an example case study of a suspended 45m2 house slab, priced on average UK material costs, Agilia™ was seen to save £291.45 on total as-built costs when power floating could not start promptly. Agilia™ removes issues observed with conventional concrete practice of water addition, insufficient compaction and curing.

  3. 3. Conditions Agilia™ Horizontal can only be laid when the air temperature is between 5oC and 30oC. The substrate must not be frozen and ideally should be within the above temperature range. Setting out levels The thickness of the concrete from the highest point of the prepared substrate should not be less than 50mm and should incorporate measures to counter plastic shrinkage. To adequately set out the levels before placing the concrete, the highest point should first be found. To easily identify the thickness to be laid a series of tripods with a height adjustable indicator should be used. A tripod should be placed at the highest point to denote the top of the finished floor and a nominal minimum thickness of 75mm. Other tripods should be placed at two to three metre intervals across the floor and the indicators set using a laser-levelling device with the first tripod as the datum. Slump-flow measurement When Agilia™ Horizontal arrives on site, the slump-flow of the material should be 650mm – 750mm when measured using the appropriate equipment. If the mix is outside of the target range, then advice should be sought from your Lafarge Readymix representative as to the appropriate course of action. Pump priming If the concrete is to be pumped, prior to pumping it is essential that the pump is primed. The pipes must be systematically “lubricated” with a slurry made up of approximately 10kg of pure cement mixed with 10l of water. The slurry should be fed through the pipes and fully recovered at the other end before any of the concrete is discharged. Pumping When placing the product, the hose should be held approximately 500mm from the substrate. The pipe should be moved in a sweeping motion and should not be held stationary above any fixed point. Agilia™ Horizontal should be poured until the pre-set levels, as denoted by the tripods, have been reached. Dappling When the material has been placed to the desired levels within a room/ area, it should be dappled immediately to obtain the best surface finish.The T-bar should be moved across the surface of the concrete with a dappling motion to generate a wave-like ripple across the surface. The dappling should occur in two directions, the second being perpendicular to the first. The first pass should be a deep pass to approximately two-thirds of the depth of the concrete, the second a light pass over the surface. Curing Following placement, a curing membrane should be sprayed over the surface using a mist sprayer. Care should be taken to follow all relevant health and safety procedures when using the curing membrane, including goggles and respiratory equipment. It is essential to ensure complete coverage of the surface as per manufacturer’s guidelines. Following placing The surface will be suitable for light foot traffic after 24 hours and can be worked on after a period of 72 hours from placing. The slab should not be loaded with palletised materials until at least seven days. Partitions can be erected after a minimum of seven days from the time of placing. Floor finishes should ideally be applied within a 60-day period after placing. The slab should be protected from excessive winds or drying for 48 hours after placing. ©DaveBird/TristanPoyserPhotography©DaveBird/TristanPoyserPhotography©DaveBird/TristanPoyserPhotography
  4. 4. Lafarge Aggregates Concrete UK Granite House, PO Box 7388 Watermead Business Park, Syston Leicester, LE7 1WA Tel: 0870 336 8258 Lafarge Aggregates Limited registered in England and Wales 297905 Bay sizes (when installed without crack control mesh reinforcement) Saw cut joints should be detailed at 40 times the depth of the slab (in mm) e.g. A slab that is 75mm deep = 40 x 75 = 3,000mm, therefore joints must be at 3m x 3m. Fibre Solutions for the replacement of Steel Mesh in Flat Slabs Agilia™ Horizontal can now be combined with various fibre technologies to facilitate the removal of crack control mesh in slab construction. The fibres are distributed evenly within the Agilia™ Horizontal concrete and the material is placed and finished in the usual Agilia™ methodology. Depending on the volume and type of steel mesh initially specified, either macro-synthetic or steel fibres can be added to offer a cost effective alternative to traditional crack control mesh. This dispenses with the need to procure traditional mesh, to take delivery of it and store it on site, before finally cutting and placing it in the slab. Agilia™ with macro or steel fibres can therefore provide financial, logistical and health and safety benefits. A design service is also available upon request if required; please contact your Lafarge Representative for further details. Safety precautions The use of safety goggles, hard hat, ear defenders and gloves is recommended when placing concrete. First Aid Eyes: Immediately flush eyes, including under lids, with water for at least 15 minutes to remove all particles. If necessary, seek medical advice. Skin: Wash skin with cold water and a pH neutral soap as soon as possible, except where open wounds are visible. Attention should be paid to wounds and fresh scars which should be covered with protective paraffin gauze. Seek medical help in cases of prolonged contact with wet concrete. Ingestion: Rinse mouth with clean water. If swallowing has occurred drink plenty of milk or water. Do not induce vomiting. Seek medical attention immediately. Inhalation: Move to fresh air. If symptoms persist seek medical attention. Disclaimer - The information contained in this leaflet is based upon knowledge and experience of the materials used in the manufacture of the products.
