As we predicted, the new Putzmeister M20 4-section concrete pump<\/a> has rapidly become one of the most popular pumps in the fleet. It has been in such great demand that we have had to order more to meet customer demand. <\/p>\n<\/div>\n<\/p>\n<\/p>\n

It is a popular pump because it is so versatile. Mounted on a short wheel-base Mercedes 1829 and having a very narrow footprint when set-up, it can be used in the tightest of city sites and also in residential areas. The 4-section boom, with low unfolding height makes it perfect for working in industrial buildings. <\/p>\n

<\/p>\n

And even when the boom cannot be used to its full advantage, the 90 cubic metre per hour \/ 78 bar pump unit is well suited to pipeline jobs. At Ardra Road, Enfield, P.J. Carey (Contractors) Ltd<\/a> used the M20\/4 to pump concrete into the ground floor office of their warehouse contract for Bestway Holdings. <\/p>\n

The easiest way to place the concrete was for the pump to remain outside the building, boom in through the doorway and then extend the line by 24 metres \u2013 5 steel pipes and 3 hoses. The experienced concrete gang were adept at moving the hoses around the floor and stripping back the pipes towards the pump, as the floor progressed. <\/p>\n<\/div>\n<\/p>\n<\/p>\n

By the end of the day the gang had put down and sealed the membrane, installed 2 layers of mesh, placed and float finished 65 cubic metres of concrete to construct the slab. There were no complaints about productivity here! <\/p>\n

<\/p>\n

The main warehouse floor is to be constructed using steel-fibre reinforced concrete. This is used for super-flat floors where durability and high abrasion resistance is required. The high-strength concrete base mix is delivered to site and a superplasticiser and steel fibres are then added to the mix. After thorough mixing, the load is ready to be pumped.<\/p>\n<\/div>\n<\/p>\n<\/p>\n

Camfaud conducts these floor pours on a regular basis – one such pour being the distribution centre for Turners (Soham) Ltd<\/a>. To check the access for the main floor pour the pump was driven into the building and with a travel height of only 3400 mm there was room to spare. <\/p>\n
